BIOGRAPHY:
Justin Zuniga is a PhD doctoral candidate in Chemistry at the 麻豆原创, with a Master of Science in Chemistry (2017) from Oakland University (Rochester, Michigan) and a Bachelor of Science in Chemistry (2013) from James Madison University (Harrisonburg, Virginia). He has 10+ years of industry experience in analytical chemistry. His expertise is liquid chromatography mass spectrometry based non targeted chemical characterization to identify extractables and leachables for medical devices. His industry work focused on supporting regulatory compliance and toxicological risk assessment. He also led method development and validation projects to meet FDA criteria in support of regulatory submissions. He is passionate about reducing reliance on animal models in toxicology by using analytical chemistry to strengthen nonanimal testing approaches so they can meet regulatory expectations with confidence.
RESEARCH:
Under the co-advisement of Dr. James J. Hickman (Chair) and Dr. Melanie Beazley, Justin鈥檚 doctoral research builds an analytical chemistry framework that uses Human-on-a-Chip systems to study pharmacokinetic behavior and translational toxicity through the applications of mass spectrometry. His area of focus includes metabolomics and chemometrics while measuring chemical disposition and biological responses, separate matrix driven variation from true signals, and support reliable interpretation. He also integrates quantitative structure modelling with machine learning to predict chromatographic retention and related chemical behaviour, streamline method development, and identify relationships across analytical, biological, and environmental measurements.
