Ruben A. Chavez, Ph.D., is a Postdoctoral Research Associate in the Department of Food Science and Human Nutrition at the University of Illinois at Urbana-Champaign, where he earned his Ph.D. in Food Science and Human Nutrition. He earned his B.S. degree in Chemistry from the University of Tampa. He is developing a near-infrared-red/visible light/ultraviolet light spectrometer to detect aflatoxin and fumonisin in corn. His research goal is to create a sorting platform with a spectrometer capable of removing mycotoxin-contaminated corn kernels and minimizing food waste while improving food safety and security. He has worked on other research projects that revolve around the analysis of sampling plans for pathogen detection in the food industry, the improvement of pathogen killing procedures in grains, and proper implementation of regulatory compliance in consumer-packaged goods. His areas of expertise are food safety, risk management, and food chemistry.
