My interests are to understand and predict approach and avoidance behaviors during odorous encounters. In naturalistic settings, odors are composed of numerous odorants that are carried in plumes. The focus of my work is to predict odor mixture characteristics based on structural characteristics of its constituent odorants and measure behavioral outcomes. The first aim is to collect reliable and valid human sensory data for a large set of odor mixtures at different combinations of concentrations. This information combined with physicochemical and structural variables will help us build predictive models that can be used with behavioral measurement tools to understand outcomes to naturalistic odors.
