Nearly half聽of the world鈥檚 citizens聽live in areas with a聽risk of catching dengue fever,听according to聽the Centers for Disease Control and Prevention.聽As聽the mosquito-borne聽illness rapidly聽spreads, especially in the Americas and Caribbean, a聽聽researcher is playing a crucial role in finding solutions.

James聽Earnest, an assistant professor at the Burnett School of Biomedical Sciences, is聽leading聽two聽new聽research projects to examine how humans build an immune response to dengue and the Zika virus over time, in pursuit of creating better preventative measures.

Tackling a Global Problem

Both聽dengue and聽Zika聽are carried by the聽Aedes aegypti聽mosquito,听which has expanded聽its habitat from Africa to tropical,听subtropical聽and even聽temperate聽areas worldwide.聽According to the World Health Organization, dengue infections in humans climbed聽from聽505,430 in 2000聽to聽14.6 million in 2024, an increase of more than 2,700%.

Dengue can be asymptomatic or cause severe pain, fatigue and high fever. Repeated infections can be fatal.

Since 2017, there have been few cases of聽Zika聽recorded in the U.S., but the disease persists sporadically in Africa, the Americas and Asia. The virus鈥 biggest health concern is聽for聽pregnant聽women because contracting聽Zika聽can increase risks for聽serious聽congenital birth defects.

While people in Mexico and Uganda聽may聽benefit聽from this research,听Florida鈥檚 location as a worldwide travel destination聽adds to聽the聽growing聽need for solutions.聽U.S.聽dengue聽cases聽are on the rise and聽have been reported in Florida, California,听Texas聽and Hawaii. Most are related to travel.聽Dengue is also prevalent in聽Puerto Rico.

鈥淭he threat to the U.S. is growing over time. … We want to be the leaders at looking at these viruses.鈥 鈥 James Earnest, 麻豆原创 Assistant Professor

鈥淲ith more favorable temperatures and with people traveling around the globe these days, the threat to the U.S. is growing over time,鈥 Earnest says. 鈥淚 think, especially here in Florida, the potential for these mosquitoes to live in these areas and start transmitting these diseases in the very near future is high. 麻豆原创 recognizes that this is an important avenue of research for this region, and so we want to be the leaders at looking at these viruses.鈥

How the聽麻豆原创聽Research Works

Earnest鈥檚 lab is focused on how the immune system responds to mosquito-borne viruses. Before arriving at 麻豆原创 in 2024, he tracked dengue via longitudinal sampling in Mexico鈥檚 Yucatan Peninsula.

Earnest is collaborating with the Uganda Virus Research Institute (UVRI) through a five-year $970,813 subcontract, part of a larger grant awarded to UVRI from Wellcome, a London-based charitable organization that supports science to solve urgent health challenges. The project aims to study immune system and antibody responses to dengue and Zika in large cohorts of people in Uganda and in Mexico.

麻豆原创 will also collaborate with Emory University on a聽$578,157聽grant from the National Institutes of Health, with Earnest subcontracted to Emory to study whether combining two current dengue inoculations used in Brazil gives humans better protection against repeat infections.

鈥淚t’s important that we understand what good and bad immune responses look like to these viruses.鈥 鈥 James Earnest, 麻豆原创 Assistant Professor

鈥淚t’s聽important聽that we understand what good and bad immune responses look like to these viruses,鈥澛燛arnest聽says. 鈥淲hen we know those factors, then聽we can try to steer people in聽the right聽direction so that their antibodies will protect them from聽disease.鈥

Earnest will coordinate with teams in other countries to regularly collect blood samples and measure antibody production to get a comprehensive look at how different people鈥檚 bodies react to dengue and Zika over time. The samples will be collected and processed in Mexico and Uganda, and Earnest will analyze the results in his lab.

鈥淚 think what’s unique about聽this work is that we鈥檙e聽following people over time and not necessarily聽just聽when they get sick,鈥澛燛arnest says.

His research focuses on B cells, which are white blood cells that make antibodies and help the body remember how to fight infections. By tracking how聽people鈥檚聽B cells change over time, his team aims to understand how immune responses differ across regions.

In a related project with Emory, the lab will聽identify聽the most effective memory B cells and antibodies induced by two existing methods of inoculation for dengue, then test whether combining those methods in Brazilian trial participants produces a stronger immune response.

Students Aim to Save Lives Through Lab Work

With this new research,听Earnest鈥檚 lab has welcomed聽two new 麻豆原创聽students聽who have聽personal聽experience聽with聽dengue and聽Zika.

Maiesha聽Mahmood, a聽second-year聽biotechnology聽master鈥檚 student,听is from Bangladesh, where the threat of dengue looms.

鈥淚 have been around dengue a lot growing up,鈥 Mahmood聽says.聽鈥淚 know people who have been in hospital聽with聽severe forms聽of dengue, and聽people聽who’ve聽passed away聽suddenly.聽People become scared of mosquitos and dengue.鈥

She聽says she聽hopes聽麻豆原创鈥檚 research will someday save lives.

鈥淏ack in Bangladesh,听we don’t really have a lot of facilities that can support virology research,鈥澛爏he says. 鈥淚t was聽a huge opportunity to be able to come here and be able to work聽with Dr. Earnest.聽I want to continue looking into these kinds of聽viruses聽and聽find聽a way to help people who keep suffering from聽these聽diseases.鈥

叠谤耻苍辞听笔颈苍丑别颈谤辞听鈥25, a first-year Ph.D. candidate,听joined Earnest鈥檚 lab聽to further his education and hopes research will聽help people close to him.

麻豆原创 Alum, Physician Gives Undergraduates Unprecedented Experience in Medicine /news/ucf-alum-physician-gives-undergraduates-unprecedented-experience-in-medicine/ Thu, 09 Oct 2025 15:09:56 +0000 /news/?p=149253 The Dr. Gideon J. Lewis鈥 Surgical Internship Program offers select pre-med students an opportunity to experience patient care, research and surgical procedures firsthand.

]]>
A 麻豆原创 alumnus who is a nationally recognized foot and ankle surgeon continues to give back to his alma mater by offering a unique Surgical Internship Program to undergraduates who are aspiring physicians.

Each semester, Gideon Lewis ’04‘s unique internship provides three or four pre-medical students exposure to the operating room alongside community surgeons. Interns don鈥檛 just stand in the corner and observe. They participate in patient care and research and get a firsthand understanding of surgical procedures and medical pathologies.

Over the past 15 years, Lewis鈥 internship has trained 85 interns and 98% of them have gone on to medical school, at universities including 麻豆原创, Case Western, Harvard, Miami and University of Pennsylvania.

鈥淭his program was born from a desire to provide students with something I never had 鈥 hands-on, immersive exposure to surgical medicine while still in college,鈥 says Lewis, who is an affiliated faculty member with the 麻豆原创 College of Medicine and director of the Foot & Ankle Sports Medicine Institute. 鈥淚t鈥檚 incredibly fulfilling to see former interns now thriving as medical students, residents and even practicing physicians.鈥

Deborah German, 麻豆原创鈥檚 vice president for health affairs and founding dean of the College of Medicine, praised Dr. Lewis鈥 commitment to education. 鈥淲hen I came here to build this medical school, I did not know that I would find such generous and talented physicians as we have in our community,鈥 she says. 鈥淒r. Lewis is an example of someone who exemplifies the portion of the Hippocratic Oath that says each of us must be committed to training the next generation of doctors.鈥

How the Program Works

The 麻豆原创 Surgical Internship Program is designed to bridge the gap between academic learning and real-world clinical exposure for undergraduate students interested in careers in medicine.

The internship selection process is selective and rigorous. Candidates must have at least a 3.5 grade point average, have taken both Human Anatomy and Human Physiology at the Burnett School of Biomedical Sciences, have a letter of recommendation and participate in an interview with internship leaders. Interns spend at least eight hours a week with Dr. Lewis鈥 team, including time in operating rooms at AdventHealth Winter Park,听Downtown Surgery Center, and Foot and Ankle Sports Medicine Institute.

They also gain insights into patient interactions, clinical decision-making, and the humanistic side of healthcare. Participants are mentored by Lewis and a team of experienced providers across multiple specialties. Mentors include community physicians in neuro, vascular, orthopedic, plastic, trauma and general surgery.

鈥淭his participation with so many different physicians makes this one of the most unique and sought-after undergraduate medical experiences in the country.鈥 鈥 Gideon Lewis ’04, alum and physician

鈥淭his participation with so many different physicians makes this one of the most unique and sought-after undergraduate medical experiences in the country,鈥 Dr. Lewis says.

Mark Chaet has been one of those participating physicians. A pediatric surgeon at Orlando Health Arnold Palmer Hospital for Children and Advent Health Children鈥檚 Hospital, he is now dean of the Florida State University College of Medicine鈥檚 Orlando Regional Campus. He says the mentorship program is successful because it involves 鈥渋ncredibly motivated and enthusiastic students who are new to the world of medicine.鈥 And as a practicing surgeon, he says the 麻豆原创 students 鈥渞eally invigorated my love for teaching.鈥

麻豆原创 students shadowed Chaet during a variety of pediatric surgical procedures, including hernia repairs, chest reconstruction and removal of benign growths. Many of the treatments were done at the surgery center, allowing students to learn and interact with their physician mentor in a smaller, less intimidating session, he said. 聽They also had the opportunity to see the dynamics of how a pediatric surgical team works with frightened young patients and their families. Chaet says such real world experiences are critical for pre-med students to really understand what it means to be a doctor and to decide if the challenging career is right for them.

鈥淒r. Lewis鈥檚 program is unique and one of the best internship experiences I have seen because he allows our 麻豆原创 students to be immersed in a clinical environment,鈥 says Kersten Schroeder, coordinator the 麻豆原创鈥檚 Burnett School of Biomedical Sciences Clinical Internship Program. 鈥淒r. Lewis allows 麻豆原创 students to work with him and see the collaborative effort it takes with other specialties to help patients on their way to the healing process.鈥

Interns are required to write and present a surgical case study and Chaet says the presentations he saw from 麻豆原创 undergraduates were comparable to those done by medical students and resident physicians.

Current and past interns often have the opportunity to learn suturing techniques during workshops with Lewis and participate in sessions with representatives from medical device companies, athletics organizations and business leaders. Those who complete the internship have the chance to come back as program administrators. The mission, Lewis says, is to train young people to pay forward their blessings and opportunities.

Students Say Surgical Experience Is Life-Changing

Taylor Duffy ’20 and Emily Larson ’25 are two of those students.

Duffy is now a second-year M.D. candidate at the University of Pittsburgh School of Medicine. He鈥檇 never been in an operating room before the internship and said the hand-on surgical workshops and mentoring clarified his dreams and gave him the confidence to pursue them. He hopes to become an anesthesiologist and said he carries with him in medical school the clinical insights, professionalism and leadership skills he learned in the program. He also carries important life lessons.

鈥淒r. Lewis taught me to take advantage of every opportunity I was given and then use it to lift up others.鈥 鈥 Taylor Duffy ’20, student

鈥淒r. Lewis taught me to take advantage of every opportunity I was given,鈥 Duffy says, 鈥渁nd then use it to lift up others.鈥

Larson is now an assistant director for the internship, where she has grown her leadership skills as she helps provide important learning experiences for new cohorts of 麻豆原创 pre-med students. She still remembers meeting with a patient who had multiple questions and worries before surgery. Larson worked closely with the patient, writing down all the information she wanted to know. When the doctor arrived moments before surgery began, the patient said she didn鈥檛 have any questions or concerns because of Larson鈥檚 dedicated care.

鈥淭he 麻豆原创 Surgical Internship Program has been invaluable to my pursuit of a career in medicine,鈥 she says. 鈥淒r. Lewis鈥 mentorship has inspired me to become a better patient advocate, leader, and future physician.鈥

麻豆原创 Researchers Fight Breast, Prostate Cancer with Targeted Therapies Backed by 2 New Grants /news/ucf-researchers-fight-breast-prostate-cancer-with-targeted-therapies-backed-by-2-new-grants/ Thu, 18 Sep 2025 13:13:03 +0000 /news/?p=149000 Strengthened by community and engineering partnerships, Annette Khaled furthers her work with the promising peptide Z-TOP that disrupts cancer cells to keep them from spreading.

]]>
A 麻豆原创 team of researchers is refining its game plan to tackle cancer.

Annette Khaled, who leads the College of Medicine鈥檚 cancer research division, recently received more than $2 million in grant funding to expand her work with Z-TOP, a peptide she discovered in 2012 that stops the spread of metastatic cancer cells. She is collaborating with colleagues to design a better cellular delivery system for the treatment.

An almost $258,000 grant through the Casey DeSantis Cancer Research Program鈥檚 Florida Cancer Innovation Fund will help Khaled鈥檚 team further their efforts to stop metastatic breast cancer by disrupting the cellular activities that allow cancer cells to spread.鈥疉nd nearly $1.8 million in funding through the U.S. Department of Defense (DOD), in partnership with the Orlando Veterans Affairs Healthcare System, will allow her to develop the treatment for men with late-stage metastatic prostate cancer.

Khaled says her research has expanded thanks to the support of the Orlando Sports Foundation, which funds cancer research through sports-related fundraising events. The nonprofit鈥檚 flagship event is the StaffDNA Cure Bowl, a unique college football game with the goal of ending cancer.

鈥淲hen you get funding for a research project, you can only do the work that is described in the specific aims of the project,鈥 she says. 鈥淭he donations from the Orlando Sports Foundation do not have this limitation.鈥疻ithout their support, I would not have been awarded the DOD grant. Using the donations, I was able to generate the preliminary data that made me competitive for the DOD and the Florida Department of Health (FDOH) grants we received this year.鈥

Alan Gooch 鈥84 鈥89MA, CEO of the Orlando Sports Foundation and executive director of the StaffDNA Cure Bowl, says he鈥檚 grateful to continue partnering with 麻豆原创.

鈥淲e鈥檙e all about bringing teams together,鈥 says Gooch, who played football at 麻豆原创 and later coached the team for 22 years. 鈥淥ur relationship with Dr. Khaled is outstanding, and we are honored to continue to partner with her and sponsor her research.鈥

The Science Behind Khaled鈥檚 Work

The two new grants expand Khaled鈥檚 portfolio of research to understand how and why cancer cells spread.

鈥淐ancer treatments are very effective when the cancer is localized, but the problem is that cancer doesn鈥檛 stay at one site,鈥 she says. 鈥淚t spreads to other sites of the body. Usually, the cause of death is not the primary cancer, but metastasis.鈥疨reventing that can be a cancer cure, and that is what we鈥檙e looking at here in our lab.鈥

Khaled鈥檚 latest research focuses on the spread of cell fragments called extracellular vesicles that are shed by cancer cells during the early stages of the disease. These vesicles are resilient to early cancer treatment and can travel through the bloodstream, acting as tumor 鈥渟eeds鈥 by preparing future sites for metastasis.

The vesicles are mediated by a molecular structure called a chaperonin. Chaperonins help fold proteins that support the body鈥檚 normal cell function. But cancer cells hijack the folding process because they need more chaperonins to grow and spread.

Khaled鈥檚 breast cancer research project aims to distinguish which chaperonins help facilitate cancer cells’ growth and stop them without harming normal chaperonins. She hopes to develop a treatment that could regularly deliver her peptide to cancer patients to prevent metastasis. Patients, Khaled says, could receive her treatment while they are receiving chemotherapy and radiation to kill the original tumor.

Her prostate cancer research will confirm the chaperonin as a viable treatment target for prostate cancer, and if so, optimize the peptide specifically for use in men who have lethal forms of metastatic prostate cancer.鈥疷nlike breast cancer treatment, which seeks to prevent metastasis, prostate cancer research will see if a strengthened variant of the peptide can eliminate cancer that has already spread.

Fielding a Team Against Cancer

In the lab, Khaled鈥檚 peptide has shown success in preventing cancer cells from spreading. The challenge is how to engineer and deliver the treatment. For that, she is collaborating with Lorraine Leon, associate professor of materials science at 麻豆原创鈥檚 College of Engineering and Computer Science.

They are working to create a system that delivers the peptide to where the cancer has spread and at the same time protects the peptide from being destroyed in the bloodstream by the body鈥檚 immune and digestive systems.

鈥淭he College of Engineering and Computer Science is a great collaborator,鈥 Khaled says. 鈥淣ormally this peptide is very fragile but we鈥檙e working with materials sciences to create a protected peptide and then find [a] way to get it to the right spot. By having a variety of expertise and interests, we can work together to find new technologies and new ways to combat cancer.鈥

Leon specializes in biomaterials and polymer science. Her team studies how to build and program molecules to form assemblies for many purposes, including biomedical transport. She developed a specialized polymer that binds to the peptide, forming a large, water-soluble molecule. This allows it to travel easily through the bloodstream while keeping the peptide intact as it reaches its destination. The system drives the molecules to form self-assembled structures called micelles, which are assemblies of around 100 or so individual molecules, Leon says.

鈥淚n addition, we can tune the shape of these micelles, decorate them with targeting elements and make mixed versions of them where we incorporate different functionalities,鈥 she says. 鈥淥ur original designs have had great preliminary results so far. We will continue to optimize the designs moving forward.鈥

Leon is excited to team up with Khaled, and she says she looks forward to achieving more breakthroughs together as the projects progress.

鈥淲orking with Dr. Khaled has been very fun,鈥 she says. 鈥淥ur labs really complement each other. This is the beginning of a very long collaboration.鈥

Khaled and Leon are also working with Cancer Specialist and Associate Professor of Medicine Deborah Altomare, along with Burnett School of Biomedical Science Biostatistician Xiang Zhu, on the prostate cancer research project.

Khaled says strong research and community collaborations are critical to beating cancer.

鈥淐ancer is a tough enemy,鈥 she says. 鈥淏ut we have a great team.鈥

These studies are the first phase of preclinical research that may lead to new drugs in the future.

麻豆原创 Medicine-Engineering Program Trains Students for Future of Healthcare /news/ucf-medicine-engineering-program-trains-students-for-future-of-healthcare/ Tue, 22 Jul 2025 13:00:39 +0000 /news/?p=148283 A unique partnership between 麻豆原创鈥檚 College of Medicine and College of Engineering and Computer Science is allowing students to better prepare for a multidisciplinary medical field.

]]>
Pavan Senthil was inspired walking through a convention hall and seeing the technology that doctors and engineers had created for people with disabilities. Wheelchairs that worked even if a person couldn鈥檛 use their arms and legs. artificial intelligence-assisted robots that provided 24/7 care at home and reported any emergencies to the patient鈥檚 healthcare team. Training tools that helped stroke patients regain their fine motor skills.

And that鈥檚 when he understood the promise of his medicine-engineering double degree (MEDD) from 麻豆原创.

The unique partnership between the College of Medicine and College of Engineering and Computer Science allows undergraduates to earn two baccalaureate degrees 鈥 one in mechanical engineering or any other engineering discipline 麻豆原创 offers 鈥 and one in biomedical sciences. The program recognizes that the future of healthcare is in technology and that the workforce needs trained professionals who can understand the biology of disease and the engineering principles to create new healthcare solutions.

MEDD is demanding, requiring 163 credit hours to earn the two degrees. To date, seven students have completed the program.

鈥淭he MEDD program is probably the most challenging undertaking at 麻豆原创 on the undergraduate level,鈥 says William Self, professor of medicine who leads undergraduate education at the Burnett School of Biomedical Sciences and helped create the medicine-engineering program. 鈥淭his small cohort of scholars are driven by their desire to help mankind in the areas of healthcare and medicine through the engineering principles they learn along the way. I am so proud of these students for their drive and perseverance to complete this path and look forward to seeing how they impact society in the future.鈥

Senthil will graduate in August and hopes to work for a company that makes assistive devices or create his own start-up. Fellow Knight Michael Meyers ’25 graduated in the spring and will begin his master鈥檚 in electrical engineering this fall at 麻豆原创. He wants to develop better ways to diagnose diseases through enhanced imaging technologies, such as AI-assisted X-rays and non-invasive visual biopsies.

Limbitless Provides Inspiration for Medicine-Engineering Partnerships

Senthil always thought his future would include medical school. But while living in Texas during high school, he discovered how Texas A&M鈥檚 EnMED program encourages engineering majors to attend medical school and use their problem-solving skills to improve patient care. Senthil, a National Merit Scholar, received information from 麻豆原创 about the MEDD program and the Burnett Honors College. 麻豆原创 also offered a scholarship and a university visit. He liked 麻豆原创鈥檚 campus life and met other students who had used their MEDD studies to achieve their dreams. He decided to become a Knight.

Pavan Senthil

On campus, he became active in Limbitless Solutions, a 麻豆原创 organization that creates and provides 3D-printed, EMG-powered prosthetics for clinical trial participants. He started with technological development and then became part of the clinical research team, where he worked with patients and their families to understand how the prosthetic limbs worked and could increase independence.

鈥淲e don鈥檛 create this technology to fix someone,鈥 he says. 鈥淭he goal is to give them tools to express themselves.鈥

The Limbitless experience also provided Senthil with research opportunities. He has published research in multiple journals and presented his scientific findings at 麻豆原创 and even nationally. One of those presentations was at RESNA, the Rehabilitation Engineering and Assistive Technology Society of North America. The non-profit professional organization is dedicated to maximizing 鈥渢he health and well-being of people with disabilities through technology.鈥

Senthil was considering graduate and medical school when he saw the scope of assistive technologies on display at the conference. His new career goal 鈥 develop technology to help people.

鈥淚 want to create a device that fills a need, that enables others,鈥 he says. 鈥淢y passion is helping people improve their lives.鈥

Improving Diagnostics Through Imaging

Meyers grew up in the Orlando area. His mother is a nurse, and he always expected to be a pre-med major. Then, like Senthil, he received communication from 麻豆原创 about the MEDD program and the Burnett Honors College. 鈥淭he dual degree broadens our experience,鈥 he says, 鈥渁nd gives you a big step up in applying what you鈥檝e learned in school.鈥

He acknowledges the double degree courseload is tough, laughing as he discusses three lab courses each semester and having to train your brain to 鈥渇lip flop鈥 from memorizing microbiology terms to thinking about logical engineering processes. But he says his flip-flopping brain helped him better understand difficult subjects like immunology. 鈥淓ngineering helped me understand why and how processes are happening when the body is fighting a disease,鈥 he says.

At 麻豆原创, he used his dual training in research and in practice. He was an undergraduate research assistant in 麻豆原创鈥檚 Nanobio Sensors Lab and did internships at Northrop Grumman and Mitsubishi Power Americas.

Michael Meyers

He credits a class with 麻豆原创 Professor of Electrical Engineering Wasfy Mikhael with inspiring him to understand how imaging and signal processing can create new systems to help physicians better see diseases like cancer in the body. That will be the focus of his masters training.

鈥淭he body in and of itself, is a well-oiled machine,鈥 Meyers says. 鈥淲ith my dual degree, I want to figure out a way moving forward to make it even better.鈥

Embarking on a New Journey /news/embarking-on-a-new-journey/ Thu, 22 May 2025 14:41:37 +0000 /news/?p=146884 Tina Chiarelli has never been one to follow conventional thinking, and now she鈥檚 gone where no person has ever before to study the human-elephant conflict.

]]>
It鈥檚 easy to make assumptions when you see Tina Chiarelli鈥檚 white-coat picture and academically rich bio under her title: Associate professor of medicine in the Burnett School of Biomedical Sciences. Yes, she鈥檚 a doctoral graduate. Yes, she鈥檚 a respected educator on human anatomy.

Now brace yourself. There鈥檚 another side to Chiarelli鈥檚 CV.

She鈥檚 bagged rattlesnakes in the Appalachians, collared Bengal tigers in India, tracked spiny crayfish in Australia, studied bats and fingernail-size coqui frogs in Puerto Rico and explored dangerous underwater caves in Florida. Chiarelli the reproductive physiologist is also Chiarelli the traveling elephant biologist.

鈥淚n the culture of medical academia, we tend to eat, breathe and sleep a singular subject,鈥 she says. 鈥淪o, when colleagues and students hear what I do they say, 鈥榃ow, that鈥檚 the coolest thing.鈥 In the context of health, I think it鈥檚 important to see the world from more than one dimension.鈥

Chiarelli鈥檚 adventures stretch back decades but have just recently drawn global attention. Since late 2022, she鈥檚 been selected as a fellow with the Explorers Club, the Royal Geographical Society and the Royal Asiatic Society. In April, she embarked on her most ambitious field mission to date. For three weeks, she had the honor of carrying one of only 242 Explorers Club flags in existence as she travels by jeep, bike, foot and on the backs of animals over a 2,000-kilometer path in Nepal. It鈥檚 a route that has never been trekked by humans, though it has often been followed by elephants. And that鈥檚 why her team of three 鈥 a guide, a guard and Chiarelli 鈥 is going.

鈥淭he pathway has been fragmented over the years and has heightened what we know as 鈥榯he human-elephant conflict,鈥欌 she says. 鈥淚ndigenous people have been resettled into these areas, but it鈥檚 placed them in these corridors that elephants have used for centuries to migrate. Deforestation has made the situation worse for people who have no other living options and for elephants trying to find shelter and food.鈥

To Chiarelli, it isn鈥檛 productive to ask which species belongs and which one is encroaching. She wants to move the human elephant conflict closer to human elephant solutions.

鈥淚t鈥檚 a pipedream to think landscapes and habitats will be replenished to what they once were,鈥 she says, referring to the elephant population in Africa, which has declined from 3 million to 400,000, and Asia, where only 27,000 elephants remain. 鈥淭here鈥檚 a push and pull on natural resources for human needs and elephant needs. Nothing will improve until we first reduce daily hardships on the people. When they鈥檙e no longer struggling for food, education and medical needs, then they can focus on being stewards of the environment.鈥

She believes the way forward can be found along the forgotten path.

Chiarelli makes this clear: She didn鈥檛 go to Nepal as a first-world academic.

鈥淚 would never tell [someone] what to do just because I have college degrees,鈥 she says. 鈥淎ssumptions don鈥檛 work in places like this.鈥

Even satellite imagery of the pathway has even been deceptive, showing what appears to be lush protective forest rejuvenated from mass clearing in the 1900s. The picture, however, is very different from the ground. The fast-growing trees planted mostly to be cut for infrastructure do not provide a protective canopy for elephants, leaving them to wander into farms and tribal villages. And so, Chiarelli will use only two research tools: a curious mind and a listening ear.

鈥淭here鈥檚 a caste system in that region of Nepal. People in lowest part of the caste have no voice. Many of them have no formal education and little contact with people outside their villages. They can give us a better understanding of what needs to change, but no one has gone in to listen to them and document what we call 鈥榯raditional ecological knowledge鈥 鈥 wisdom through storytelling 鈥 until now.鈥

Chiarelli knows firsthand what it鈥檚 like to live in challenging circumstances. She lived in a trailer while growing up in rural Maryland. Her mom and dad had to work just to get by, and never finished high school.

鈥淭here weren鈥檛 a lot of opportunities,鈥 she says. 鈥淲hen I told a guidance counselor in high school that I planned to go to college, he said, 鈥榃hy? College isn鈥檛 for people like you.鈥欌

Chiarelli remembered those words, but never followed them. She鈥檇 already begun to uncover opportunities in nature. She climbed trees to look into birds鈥 nests and crawled among the undergrowth to find snakes.

鈥淭o me, it was an explorers paradise,鈥 she says.

She didn鈥檛 know there could be any other place in the world until her grandfather gave her boxes of old National Geographic magazines. Inside one box she found a book, Through Hell And High Water, compiled by members of the Explorers Club. The world began to open for Chiarelli when she enrolled at West Virginia University, with plans of becoming a veterinarian. She loved learning, yet she didn鈥檛 allow school or being a woman to confine her.

鈥淚 always thought there was a bigger purpose out there for me, and I鈥檇 eventually find it,鈥 Chiarelli says.

This quest led to an internship at the Roger Williams Park Zoo in Rhode Island. During her first rotation there, she worked with doctoral researchers trying to determine how a red panda鈥檚 health problems related to her reproductive cycle. The research opened Chiarelli鈥檚 eyes. The next rotation changed her life.

鈥淚 went to the elephant barn and everything just stopped,鈥 she says. 鈥淚鈥檇 watch these elephants named Kate, Ginny and Alice comfort each other with their trunks. I saw them make people laugh. There鈥檚 a heartbreaking side to elephants in captivity, but once they鈥檙e here we have to give them the best care and move forward.鈥

Chiarelli never looked back. When she told a mentor that she wanted to work with elephants in their natural habitat, he said she鈥檇 have to find her own way to make it happen.

It was exactly what she wanted to hear.

鈥淢y overactive imagination has served me well in teaching and exploring. To me, the sky is always the limit.鈥

I must be watching someone else鈥檚 life. This is how Chiarelli feels whenever she goes to faraway places to live out of a backpack and document everything she sees.

鈥淎s [someone] who grew up in a trailer, every type of exploration has been like chasing dragons off the map for me,鈥 she says. 鈥淲hen I take a step back, it鈥檚 surreal.鈥

The doctoral degree and white coat in Chiarelli鈥檚 bio are surreal, too.

鈥淢y overactive imagination has served me well in teaching and exploring. To me, the sky is always the limit,鈥 she says.

And now here she is, carrying one of the Explorers Club flags that have been to the North Pole, South Pole, bottom of the oceans, summit of Mount Everest and to the moon. 鈥淢aybe a student or colleague who feels the odds are stacked against them will be inspired from knowing where I鈥檝e been, where I am now and where I intend to go.鈥

Graduate Students Share New Discoveries to Treat Disease /news/graduate-students-share-new-discoveries-to-treat-disease/ Fri, 18 Apr 2025 19:05:53 +0000 /news/?p=146481 鈥淚t is a great feeling when you know that聽聽you鈥檝e provided knowledge that can help bring us one step closer to treating a disease,鈥 麻豆原创 Ph.D. Candidate Nasser Yousef says.

]]>
Nasser Yousef came to 麻豆原创 as an undergraduate biomedical sciences major, unsure if he would pursue a career as a physician or a scientist. Today, as a Ph.D. candidate at the Burnett School of Biomedical Sciences, he has dedicated himself to medical research because he says scientific discovery can impact patients worldwide.

He presented his research at the Burnett School鈥檚 spring Graduate Research Symposium, taking first place for his findings on how acute viral infections differ from persistent viral infections, with a goal of developing better therapies to treat them.

鈥淚鈥檝e always had an interest in infectious diseases and how to combat them since they鈥檙e an ongoing threat and we need to stay one step ahead of them,鈥 Yousef said. 鈥淚 hope my research provides the scientific knowledge necessary to develop effective therapeutics.鈥

This year鈥檚 presentations included the effects of cancer drugs on the heart, mapping the stomach to better understand abdominal pain and a DNA analysis of patients with rare genetic diseases. The event鈥檚 goal is to better prepare young scientists to present their findings to peers, funding agencies and potential employers.

鈥淭his symposium is like a real-world scientific conference. You have to be prepared to present and answer questions from experienced researchers,鈥 said Jackie Zhao, a biomedical sciences professor and organizer of the symposium.

Each fourth-year Ph.D. student and second-year M.D./Ph.D. students required to present research at the symposium, but less senior Ph.D. candidates can be invited if faculty judge their research to be stellar. That was the case of third-year Ph.D. student Eugene Baffoe, who placed second in the competition for a study on new insights into how T-cells protect us against influenza.

In the months leading up to the presentation, graduate students compile their reserch data, create a presentation and write their abstracts. After their presenting, students answer questions from Burnett School faculty, who, in addition to teaching, conduct research in areas including cancer, neurodegenerative and infectious disease.

Zhao said he is seeing a trend of more graduate students like Yousef who are focused on using their scientific studies to improve patient care. 鈥淓very student is thinking about the problems they can solve and the cures for diseases,鈥 he said. 鈥淭hey usually have a family member, or someone in their lives who suffers from an illness, and they want to contribute to research that helps people.鈥

Yousef examined the immune system to understand how the body struggles to fight persistent infections. When our bodies are infected with a virus, the immune system sends proteins called C鈥 to destroy the virus and infected cells. Because acute cells are sensitive to C鈥, they are destroyed by the protein quickly. However persistent infections are almost completely resistant. Yousef analyzed the cells and found that the persistently infected cells had a 10-fold increase in vitronectin, a gene that resists C鈥.

His study provides valuable insight into how persistent infection cells resist the immune system, opening the door for future researchers to develop therapeutics.

As he completes his Ph.D., Yousef is working in the lab of Griff Parks, who directs the Burnett School and is a nationally recognized virologist.聽聽They are researching the body鈥檚 immune responses to Paramyxoviruses, which are responsible for many diseases in humans and animals, including measles, mumps and respiratory infections

Ph.D. candidate Jonatas Rolando presented his research on how a common drug used to treat leukemia causes harm to the patient鈥檚 heart. He said they prepared him for the next step he鈥檒l face in his career.

鈥淧resentations and conferences are a big part of being a scientist,鈥 he said. 鈥淭he most important thing in science isn鈥檛 the papers you publish, but how you bring the knowledge and info to society so they can use it to discover new things.鈥

麻豆原创 biomedical sciences graduate students and postdoctoral researchers recently shared their innovative research on improving health 鈥 including ways to create better flu shots, treatments for Lyme disease and diagnostics for colorectal cancer.

This year鈥檚 Burnett School of Biomedical Sciences Graduate Research Symposium featured more than 50 research projects. Students shared their findings with faculty and competed for cash prizes for the top research.

The symposium provides young researchers with the opportunity to analyze their data and create compelling presentations that can ultimately get support from research funding organizations, says Jackie Zhao, a Burnett School professor and symposium chair.

鈥淚t takes a lot of effort and hard work to … get the data for these presentations. Without that, you cannot have a presentation,鈥 he says. 鈥淪tudents also need to … pull that together into a good story that they can continue to work on 鈥 from the bench, into clinical trials and potentially into a new drug.鈥

Second-year doctoral student Aaron Beaird joined the Burnett School with a passion for understanding infectious diseases. He discovered a mentor in Tara Strutt, associate professor and College of Medicine immunology researcher.

Beaird’s research focuses on better understanding influenza so medicine can develop one complete vaccine, rather than changing the flu vaccine every year based on the disease鈥檚 newest strain.

Current vaccines are designed to attack influenza鈥檚 surface proteins, which change constantly. Beaird is looking at ways to attack the virus鈥 internal, more stable proteins to create a superpowered vaccine patients might only have to take once.

Generally, vaccines work by introducing a weak or inactive version of a virus to the body. This allows the immune system to recognize the virus as a threat and remember how to fight it when you鈥檙e exposed to the flu.

However, not all of the body鈥檚 memory cells are created equal. Beaird鈥檚 research is examining the makeup of the strongest memory cells to see how future vaccines can be developed that program these cells to help the body create superpowered defenses against the flu.

Beaird says that the conference gave him experience on the best ways to present his scientific discoveries.

鈥淗aving the opportunity to talk with my peers and faculty who understand this research and are contributing to the advancement of science is super exciting,鈥 he says. 鈥淲hen we go to conferences, we are going to have to present posters, and you don鈥檛 want that to be your first time doing it, so you need practice presenting.鈥

The event also allows undergraduates and new graduate students to experience the variety of research happening at the Burnet School of Biomedical Sciences. Its faculty researchers are focused on finding cures and treatments for the diseases that plague humanity 鈥 including infectious, cardiovascular and neurodegenerative diseases and cancer.

“The Burnett research symposium is a great opportunity for our students and postdocs to showcase their research work to their peers and faculty,鈥 says Saleh Naser, the Burnett School鈥檚 associate director of graduate studies. 鈥淚t also allows our new students to be introduced to the ongoing research at the Burnett labs.鈥

]]>
Three 麻豆原创 faculty members have been awarded fellowships by the 麻豆原创 Office of Research to advance the university’s research efforts over the coming year.

The selected fellows 鈥 Vladimir Boginski, Nichole Lighthall and Dinender Singla 鈥 will develop and implement programs that can help improve faculty grant success and accelerate the growth of the research enterprise.

Topics the fellows will focus on include research infrastructure, proposal development and specific research awards.

The fellowship begins in Fall 2024 and will continue through Summer 2025.

Meet the new Research Faculty Fellows:

Vladimir Boginski

Professor of industrial engineering and management systems and co-director of 麻豆原创鈥檚 Applied Operations Research Laboratory

How does it feel to be selected as a faculty fellow?

I am honored to be selected by the Office of Research as one of the faculty fellows this academic year. I am looking forward to the opportunity to use my experience in conducting interdisciplinary research and participating in large multi principal investigator grants to help 麻豆原创聽reach聽its strategic goals in terms聽of research funding and expenditures.

How do you hope to use this fellowship to further your research?

I hope that my experience in this role will be beneficial to my own research program development. I view this fellowship as a “two-way” opportunity. On one hand, I will be happy to offer my experience with various aspects of large grants and use it to the benefit of 麻豆原创 achieving strategic funding goals. On the other hand, I appreciate the opportunity to learn more about the high-level strategic and administrative aspects of sponsored research that the 麻豆原创 Office of Research deals with. In addition, it would be very interesting to learn about 麻豆原创 faculty research in various fields and potentially identify new opportunities for聽interdisciplinary research. Therefore, I believe that this fellowship would be beneficial both to my own academic research career and to 麻豆原创.

What is your background in research and what does your work focus on?

My research background and interests are in the broad area of network science and engineering. Networks are everywhere in the modern world: application areas are abundant, spanning the domains of big data and physical/virtual complex systems. Examples of real-world networked systems include communication networks, interdependent infrastructure networks, social networks, biological networks, financial networks and many others. Because everything is connected in one way or another, my research spans a multitude of disciplines. Although specific details of my research may vary depending on the field, the underlying broad goals are often the same: to identify nodes and links that are critical for the integrity of a network, and to optimize the connections so that each system functions more efficiently.

What else should Knight Nation know about you?

Prior to joining 麻豆原创, I was a faculty member at the University of Florida, and during my academic career I have served as principal investigator or co-principal investigator on multiple grants for over $16 million. I have always valued the exposure to聽research disciplines different from my own background, and I was honored be nominated to participate in the Frontiers of Engineering program administered by the National Academy of Engineering, which connects and facilitates collaborations between engineers across different fields. In this fellowship role, I hope to participate in initiatives to promote interdisciplinary research collaborations between 麻豆原创 faculty.

Nichole Lighthall

Associate professor of psychology, lab director of 麻豆原创鈥檚 Adult Development and Decision Lab and associate program director of 麻豆原创鈥檚 Human Factors and Cognitive Psychology Ph.D. Program

How does it feel to be selected as a faculty fellow?

I feel honored to be selected 鈥 and excited to have the opportunity to train in university leadership. The primary feeling has been joy over getting to work with 麻豆原创 faculty who want to gain more skills and success in grant development. I’ve already gotten involved in the Office of Research’s Grant Writing Academy and the faculty in that program are so motivated and excited about their research. It’s going to be very fulfilling to help them achieve their goals.

How do you hope to use this fellowship to further your research?

My primary goal for the fellowship is to enhance 麻豆原创’s success in securing funding from The National Institutes of Health (NIH) and generally expand its health-related research portfolio. As a cognitive neuroscientist working in cognitive aging, I depend on NIH funding to conduct my research. So, any success toward my fellowship goal will help my research program grow as well.

What is your background in research and what does your work focus on?

I have been studying cognitive aging since I was an undergraduate student at the University of California, Berkeley over 20 years ago. Over time, my research interest came to focus on how decision-making changes in healthy aging and neurodegenerative diseases. Most recently, my lab has been trying to understand risk factors for financial exploitation in older adults, and how we can better protect seniors from scams and fraud. To address these questions, we use behavioral and neuroimaging approaches, but also consider social and health factors that might make some seniors more vulnerable.

What else should Knight Nation know about you?If you want help with developing your own NIH grants or have ideas for initiatives that we should develop to support NIH-funded research at 麻豆原创 鈥 please reach out to me. I’m here to help you!

Dinender Singla

Professor of medicine, 麻豆原创 cardiovascular division leader and Florida Hospital chair in cardiovascular science

How does it feel to be selected as a faculty fellow?

Being selected as a faculty fellow is an extraordinary accomplishment, and I am deeply grateful for this opportunity. I feel a profound sense of pride in this achievement and am eager to contribute to the institution and its faculty.

How do you hope to use this fellowship to further your research?

This fellowship will enhance my in-depth research knowledge as I meet different faculty members, unit chairs, and deans. I took this position primarily because I want to serve the faculty at large, and I am keen to see their growth. This role allows me to mentor and guide other unit faculty, inspiring them to reach their full potential. The faculty growth is essential and will positively impact the lives of countless postdoctoral fellows and students. These insights and expertise will be highly valuable and will carry weight in shaping the future direction of different colleges, and university, which will ultimately support our community.

What is your background in research and what does your work focus on?

I have over 25 years of research experience in basic and translational research in cardiovascular sciences. I have brought more than $12 million in NIH grant funding to 麻豆原创. My major research area is stem cells and their derived exosomes for treating diabetes and anti-cancer drugs-induced cardiotoxicity. We have recently prepared specialized exosomes which can target tumors and kill them. Additionally, we have prepared exosomes to deliver drugs in the heart. This new research will lead to treat cancer patients more precisely. I am head of the Division of Metabolic and Cardiovascular Sciences in the Burnett School of Biomedical Sciences, which is part of 麻豆原创鈥檚 College of Medicine.

A $900,000 congressional appropriation will help the 麻豆原创 College of Medicine create a pathogen surveillance and research core to identify and address future pandemics.

U.S. Congressman Darren Soto recently presented the funding to Deborah German, vice president for health affairs and founding dean of the medical school, and Griffith Parks, associate dean of research and director of the College of Medicine鈥檚 . Parks is an internationally recognized virus researcher.

Congressman Soto says he is honored to secure the support for 鈥渙ur hometown medical school because we all saw, with both Zika and COVID-19, the need to study diseases to improve the public鈥檚 health.鈥

During a tour of Parks鈥 lab, the College of Medicine leaders discussed the important role Orlando can play in protecting the nation and world from infectious disease.

鈥淲e are a global tourist destination with one of the world鈥檚 most visited airports,” German says. 鈥淭he world is coming here. That鈥檚 why Orlando is the canary in the coal mine.鈥

The congressional funding will purchase genomic sequencing equipment that will allow College of Medicine researchers to identify the entire genetic makeup of viruses like COVID-19 and other microbes. Parks says such technology allows researchers to determine quickly the genetic makeup of new pathogens, a first step in identifying treatments. Microbiologists worldwide are continually monitoring pathogens 鈥 viruses and bacteria 鈥 that could lead to a pandemic.

鈥淲e鈥檙e certainly going to face more outbreaks like COVID-19,鈥 Parks says. 鈥淚t鈥檚 not if we鈥檒l have another pandemic, it鈥檚 when.鈥

The ease and speed of worldwide travel was a key element in COVID-19鈥檚 spread, Parks says, adding that a pathogen research and surveillance core at 麻豆原创鈥檚 Health Sciences Campus 鈥 located just minutes from Orlando International Airport 鈥 would help facilitative earlier recognition of potential pandemics. On any given day, Orlando鈥檚 population increases by one million visitors.

The genome sequencing equipment will also assist College of Medicine researchers focused on finding new therapies for diseases like cancer, Alzheimer鈥檚 and Parkinson鈥檚 disease, and provide research training for 麻豆原创 students seeking careers in medicine and science.

鈥淚n addition to research, our mission is to train the next generation of biomedical scientists,鈥 Parks tells Congressman Soto.

麻豆原创 Researchers Develop Nano-treatment to Help Save Florida Mangroves from Deadly Disease /news/ucf-researchers-develop-nano-treatment-to-help-save-florida-mangroves-from-deadly-disease/ Fri, 26 Jul 2024 14:33:43 +0000 /news/?p=142403 The scientists are harnessing nanoscience to concoct a special nutritional formula to fight a latent yet potentially lethal disease that is increasingly threatening mangroves in Florida and across the world.

]]>
Mangroves and palm trees are hallmarks of the Sunshine State not just for their beauty but for their immense importance to Florida鈥檚 coastlines.

Mangroves are crucial because they naturally protect coastal shores from storm damage and serve as vital wildlife habitats around the world.

Scientists at the 麻豆原创 are working to preserve mangroves in Florida and across the world from an increasingly prevalent disease-causing variety of fungi that lies dormant but become active when the tree is exposed to stressors such as temperature fluctuation, pests or other diseases.

The disease does not yet have an official name, but it is being referred to by scientists as 鈥淢angrove CNP.鈥 It is caused by a group of fungal pathogens, including Curvularia, Neopestalotiopsis, and Pestalotiopsis, that causes yellowing and spots, and gradually weaken the mangrove until it ultimately dies.

Melissa Deinys, a 麻豆原创 undergraduate researcher, and Jorge Pereira, a 麻豆原创 graduate research assistant, are working to help turn the tide by developing and testing a promising nutritional cocktail comprised of nanoparticles to strengthen mangroves and counter the pathogens. The work is through 麻豆原创 professor Swadeshmukul Santra鈥檚 (MISA) center at 麻豆原创, which is a U.S. Department of Agriculture-National Institute of Food and Agricultural recognized Center of Excellence.

Mangrove CNP in Florida was first identified as causing mangrove die-offs by Deinys in 2019 in Miami through her work with Fairchild Tropical Botanic Garden. Later, the Marine Resources Council, a non-profit organization dedicated to the protection and restoration of Florida鈥檚 Indian River Lagoon, verified and cited her efforts.

Deinys and collaborators with the MRC and Fairchild Tropical Botanic Garden have determined that about 80% of the mangroves they had sampled have tested positive for at least one of the fungal pathogen species. She says they have sampled over 130 mangroves between the Indian River Lagoon and Miami mangrove populations.

The researchers are treating the mangroves by soaking them in a nutrient solution called 鈥淢ag Sun鈥 (MgSuN), which is comprised of magnesium and sulfur nanoparticles. The mixture is a refinement of a previous graduate student鈥檚 formula that destroyed bacteria on tomatoes, Pereira says.

 

鈥淭he reason why we choose magnesium is because it is more environmentally friendly, and plants need a lot of magnesium,鈥 he says. 鈥淚 combined our magnesium formulation with a sodium polysulfide. Sulfur is one of those elements that is ubiquitous in the environment, and the idea is that you can combine both to actually enhance the anti-microbial capacity for both bacteria and fungi and you also supply key nutrients to the plants so that they can grow greener and leafier.鈥

During lab tests, the researchers say they observed growth inhibition of up to 95% when treated with MgSuN at varying concentrations compared to the untreated control.

The formula acts as a sort of antibiotic and multivitamin, and it has shown great potential in bolstering the health of infected mangroves at nurseries across Florida, Pereira says.

鈥淲e鈥檝e done some experiments, and we have tested both in vitro and in plants,鈥 he says. 鈥淲e鈥檙e working with the nurseries, and we鈥檝e seen it does kill the pathogens with no detrimental effects to the mangroves while kickstarting their health. They look great after treatment.鈥

Deinys is continuing her work with the Fairchild Tropical Botanic Garden, MRC and nurseries across Florida while staying the course on her path to graduation and furthering her research at 麻豆原创.

She began studying the fungal pathogens in 2018 in Miami prior to being enrolled at 麻豆原创 and has seen the mangroves become increasingly affected by the pathogens鈥 opportunistic nature.

鈥淏ack at the botanical gardens where I started, I would see the plants have these pathogens but not to a detrimental effect where we now see these organisms collapsing,鈥 she says. 鈥淎 mangrove nursery [The Marine Resources Council] had reached out to us, and they told us they had an insect infestation and then the whole population got wiped out by the pathogen. We鈥檙e also getting reports from places like Tampa that say areas that have more runoff are having more pathogen-related deterioration compared to 10 years ago.鈥

The fungi have been well-documented for some time, but volatile temperature changes, frequent storms and other increasing stressors open the door to the fungi taking a hold of the mangroves, Deinys says.

鈥淭hey鈥檙e called opportunistic, and they鈥檙e called that for a reason,鈥 she says. 鈥淭hey see a change in the plant and that鈥檚 when they start to take effect.鈥

How the pathogens are acquired is something that remains unclear, Deinys says. Researchers hypothesize it may be introduced through water, wind or insects, but further studies are needed to determine how it is acquired since it poses threat to mangrove health.

鈥淵ou have to study all possibilities to determine what is the vector,鈥 Deinys says. 鈥淲e鈥檝e seen papers and literature in other countries that have shown these pathogens for a long time. It鈥檚 been difficult because there is a disconnect in mangrove communities because we鈥檙e worlds apart and with different languages.鈥

The MgSuN nutrient solution is a treatment, but not a cure, Deinys says. There still are ample stressors that should be managed and mitigated, such as human-caused habitat destruction, in addition to treating the pathogens.

鈥淚 think there鈥檚 a big restoration effort to repopulate mangroves,鈥 she says. 鈥淏ut first we need to look at the health of these mangroves and the health of the ecosystem before we determine what more we should do. We鈥檙e working with mangrove nurseries to see if we can together develop solutions.鈥

Maintaining and restoring mangroves is an essential component of ecological stewardship, and it鈥檚 a passion that Deinys hopes to continue throughout her career.

鈥淚 started this project my freshman year,鈥 she says. 鈥淚 didn鈥檛 want to leave what I was doing, and I came here with a mission. I met with Dr. Santra, our PI, and he wanted to help. He gave me a lot of freedom, and I鈥檓 really grateful.鈥

Deinys says that her research at 麻豆原创 has been incredibly gratifying.

鈥淭here is a sense of community here that I found,鈥 she says. 鈥淚 joined the lab, and it felt like I found my family and that鈥檚 one of the best things to have come out of this experience. This has been one of my life鈥檚 passions, and I hope I鈥檒l always stay with this project even after.鈥

Santra is encouraged by the research conducted by Pereira and Deinys, and he is hopeful it continues to bolster mangrove ecosystems.

鈥淭he 麻豆原创 MISA center is dedicated to solving global problems that threaten agricultural sustainability,鈥 he says. 鈥淲e are excited to have another crop protection tool in our toolbox for protecting mangroves. I see the future of MagSun as a broad-spectrum fungicide, where GRAS (Generally Recognized As Safe) materials are empowered through nanotechnology.鈥

Further studies are needed to pinpoint which stressors are affecting the mangroves the most so that scientists can better preserve them, Pereira says.

鈥淚t鈥檚 very important to understand the stressors, and we need to really address if it鈥檚 a change in temperature, if it鈥檚 runoff or if it鈥檚 an additional pathogen,鈥 he says. 鈥淚n the meantime, we need to do something to prevent this damage from occurring.鈥

Researchers鈥 Credentials

Deinys graduated from BioTECH @ Richmond Heights High School, a conservation biology magnet school, where she began her research journey at Fairchild Tropical Botanic Garden and specialized in botany. In Fall 2022, Deinys joined 麻豆原创 and became a member of the Santra Lab the following spring. She is an undergraduate research assistant working towards her bachelor鈥檚 degree in biotechnology.

Pereira graduated from Universidad Nacional Aut贸noma de Honduras with a degree in industrial chemistry. He joined Santra鈥檚 lab in 2020 and is currently a graduate research assistant and working toward his doctoral degree in chemistry.

Santra holds a doctorate in chemistry from the Indian Institute of Technology Kanpur. After graduating, he worked at the University of Florida (UF) as a postdoctoral researcher and later as a research assistant professor at the UF Department of Neurological Surgery and Particle Engineering Research Center. In 2005, Santra joined 麻豆原创 as an assistant professor at the , the and the Burnett School of Biomedical Sciences. He is the director of the 麻豆原创 Materials Innovation for Sustainable Agriculture center, a USDA-NIFA-recognized Center of Excellence.
