Research Interests:
Dr. Hayes’ research group studies food choice within a biobehavioral framework, integrating traditional sensory science methods with behavioral genetics to understand biological factors that may cause individuals to like and consume some foods but not others. Special emphasis is given toward foods and beverages that have a strong potential health impact. Research in his laboratory focuses on the following areas:
• Psychophysics of taste and flavor perception
• Quantifying the impact of genetic variation in food sensations and reward
• Understanding how this variation may or may not influence patterns of food intake
• Identifying factors that drive the consumption or avoidence of alcohol, bitter phytonutrient rich vegetables, and fat/sugar mixtures
• Acquisition of preference for initially aversive stimuli, like the burn from chiles or black coffee
