My broad research interests are concerned with the sensory perception of the external chemical world. The central questions investigated in our laboratory are concerned with how animals detect and discriminate among the thousands of different chemical signals that "flood" the olfactory and taste organs. Our laboratory uses Drosophila as a model to study these problems because the Drosophilachemosensory systems are structurally and functionally very similar to those of mammals, yet they are smaller and somewhat less complex, which makes them excellent models to investigate the molecular and neural basis of olfaction and taste.
