Neural Mechanisms of Learning and Memory Consolidation in Drosophila
We use genetic, transgenic, molecular biology and ablation techniques to examine relationships between brain structure and behavior in the fruit fly, Drosophila melanogaster. How and where animals form, store and access memories are among the oldest and most intriguing questions in neurobiology, and the primary focus of our investigations. Our lab also examines other types of behavior including olfaction, locomotion, courtship, foraging and rhythmic phenomena. The polygenic architecture of quantitative and pleiotropic mutant phenotypes is a related topic of interest.
