Research Summary

Chemosensory disorders substantially impact the quality of life. Impairment of taste and smell contributes to malnutrition, cachexia, and depression in affected patients. Chemosensory loss, particularly olfactory loss, is an early symptom of Parkinson’s and Alzheimer’s diseases. The mechanisms of chemosensory disorders remain largely unknown and there is a lack of specific and effective treatment for these disorders. The primary focus of our laboratory is to identify molecular and cellular mechanisms underlying chemosensory disorders. Our recent research also investigates how damaged chemosensory structures regenerate. Moreover, our lab is actively pursuing olfactory biomarkers for neurodegenerative diseases and the bidirectional interactions between chemosensory signaling and immune regulation in extra-oral tissues.
