Marcia Pelchat


Associate Member, Monell Chemical Senses Center


Ph.D., Physiological Psychology; University of Pennsylvania

Research Summary

My research interests include: 1) food preferences, especially mechanisms of food cravings, responses to novel foods, and food preferences in the elderly; 2) chemical senses in the elderly including taste, smell, and chemical irritation; 3) genetics of individual differences in human chemosensation; and 4) neuroimaging of sensory and evaluative responses to food.
