Research Interests

Our research investigates chemical senses using methods of electrophysiology, functional imaging, immunocytochemistry, and behavior assay in transgenic mice. Current research focus is to elucidate effects of acute and long term exposure to environmental chemicals causing irritation on the chemosensory system including olfactory and trigeminal systems and to find out how the systems maintain the sensory functions during the chemical challenges adapting the environmental changes.
