Biochemical and Neuronal Mechanisms mediating Olfactory Behavior.                                                           We are using a combination of Genetics, Biochemistry, Electrophysiology, Cell Biology and Molecular Biology to undertake a molecular dissection of the chemosensory behavior in Drosophila. This relatively simple model system allows us to correlate expression of signal transduction molecules with specific subsets of olfactory neurons so we can understand chemical information processing by the brain. The recent completion of the sequence of the entire Drosophila genome is providing abundant new molecular probes to investigate these processes. Most recently we have become interested in the molecular signaling mechanisms mediating detection and perception of volatile pheromones. A recent postdoctoral fellow, PingXi Xu was awarded the $25,000 Eppendorf Prize in Neuroscience in 2005 for his work in this area.
