Research Summary

My research is directed at the molecular mechanisms underlying taste and smell signal transduction and receptor cell regeneration. The focus is on identifying and characterizing molecules that are involved in the recognition and transmission of taste and olfactory stimuli in the oral and nasal cavities, respectively, and on the progenitor cells’ differentiation and maturation in the olfactory epithelium. This work has implications for understanding the cellular and molecular basis of chemosensation under various circumstances, which may lead to effective treatments of such taste and olfactory disorders as dysgeusia and anosmia.
