- Roles of early dietary experience, taste, hormones, and the brain in control of appetite, energy balance, and blood pressure regulation. Special focus is on plasticity, hypertension, and obesity. Analyses include behavioral, physiological, and anatomical approaches.
- Current Research
- The research focuses on how the rodent peripheral gustatory system codes information about taste quality and intensity, as well as how internal (e.g. sodium deprivation, hormone levels) and external (e.g. stimulus temperature) factors influence coding using electrophysiological recording methods of whole nerve and single-cell responses and parallel psychophysical studies of taste-mediated behavior.
