Jiyoon is a Ph.D. candidate in Dr. Nitin’s Laboratory. Her project focuses on microbiological food safety engineering. She is currently working on a collaborative USDA food safety project to reduce cross-contamination during washing of fresh produce. She has developed a quantitative method to characterize the risk potential of cross-contamination between produce surfaces. Her research further involves mathematical modeling of a produce washing, which is expected to improve the efficiency of industrial washing process on reducing cross-contamination. Based on experimental studies of bacterial adhesion kinetics and chemical sanitizer reactions, computational fluid dynamics is coupled to predict the efficiency of bacterial inactivation by sanitizer in a flow system.
