Research Summary

For the past 20 years, the overall goal of my research program has been to understand chemosensory dysfunction as a disease entity, developing appropriate clinical measures of chemosensory function, identifying etiologies of dysfunction, and investigating such issues as the impact of chemosensory dysfunctions on patients, the demographic characteristics of individuals with chemosensory dysfunctions, and the prognoses for chemosensory dysfunctions. Most recently the focus of our studies has been on the role of inflammatory pathology in chemosensory dysfunction, particularly in smell loss secondary to chronic rhinosinusitis, and on the protective role of extra-oral taste receptors in nasal-sinus disease. We are also pursuing studies of plasticity in the adult olfactory system with the goal of enhancing olfactory function in aging and disease.
