My research interests focus on how odorant perception affects human psychological and physiological responses. Many organic volatile compounds can elicit an odorant and irritant response. Olfactory cues such as smoke or rotten food alert us from perils and may produce an anxious reaction. I am interested in understanding how odorant perception affects different subpopulations, e.g., asthmatic subjects (who have respiratory problems) versus non-asthmatic subjects. Our sense of smell changes during our lifespan; it decreases as we age. It can get compromised during illness processes (e.g., bacterial and viral infections) or environmental exposure (toxins and pollutants). I am also interested in studying the relationship between olfactory performance and health status.
