Research Summary

I am interested in the influence of person-to-person differences on chemosensory perception and food preference and how genetic variation explains the individual differences in the sense of taste and smell. Consumer segmentation has been my favorite analysis to understand consumers’ sensory perception and food preference during my past research. However, differences in food sensory perception between consumer segments were not well-interpreted in previous studies, although individual influences such as demographics, chemosensory ability, and food consumption habits were incorporated in those studies. Individual differences in chemosensory perception may be explained by genetic variation. My current research focuses on the connection between genetic ancestry and bitter perception and the efficacy of bitter blockers. Understanding chemosensory and hedonic biomarkers will offer great support for improving the health and well-being of specific populations as well as the development of medicine and food products.
