We want to understand how the brain processes sensory information and adapts behavior to changing internal and external conditions. Using the vinegar fly (Drosophila melanogaster) as a model organism, we focus our research on sensory processing, neuropeptide signaling, circadian biology, and the neural control of behavior. We use advanced techniques, such as neurogenetics, in vivo two-photon imaging, patch clamping, optogenetics, and circuit reconstruction, as well as a wide array of assays for innate and learned behavior.
