- Interest
- Neural basis of gustation, animal psychophysics, sensory processes, regulation of ingestive behavior, taste preferences and aversions.
- Current Research
- Assessment of taste function in mice with genetic deletions of taste receptors • Analysis of alterations in taste function and ingestive behavior associated with gastric bypass surgery • Evaluation of taste function following targeted damage in central gustatory structures • Analysis of function following transection and regeneration of gustatory nerves.
