Research Summary
For most of my scientific career, the overall goal of my research program was to understand chemosensory dysfunction as a disease entity, develop appropriate clinical measures of chemosensory function, identify etiologies of dysfunction, and investigate such issues as the impact of chemosensory dysfunctions on patients, the demographic characteristics of individuals with chemosensory dysfunctions, and the prognoses for chemosensory dysfunctions. This work has naturally fed into and helps to support Monell’s current Anosmia Research and Awareness Initiative. Most recently, I have also become involved in studies of the protective role of extra-oral taste receptors in nasal-sinus disease.
