Research Summary

My lab studies the physiology of signal transduction pathways and the regulation of these pathways in neuronal systems. We focus on peripheral sensory systems, primarily the taste system. The long term goal of the lab is to understand how signaling mechanisms are regulated within taste cells and how this regulation impacts the generation of the stimulus signal to the brain. We use molecular and physiological techniques, including patch clamp analysis and calcium imaging to investigate how signaling mechanisms function in taste cells.
