Research Summary

Dr. Small’s research focuses on chemosensation and ingestive behavior in humans using neuroimaging combined with metabolic, psychophysical and neuropsychological methods. A major focus of her current work is understanding the impact of diet on gut-brain signaling, perception and cognition. Dr. Small has also established a translational - reverse translational program of research through collaborations with colleagues working in mouse models. The Small Lab currently has a fully automated and fMRI compatible olfactometer, gustometer, and indirect calorimeter. The lab is also equipped with a mock scanner, bio-impedance device, phlebotomy suite, three subject testing rooms and a wet lab.
