I study odor information processing and memory storage using biological, computational and electronic approaches. My lab studies biological olfaction using mammalian systems whose central odor processing networks reliably compute complex predictive relationships between odor stimuli and rewards. We record in vivo from mitral cells in the mouse olfactory bulb during odor discrimination and odor learning to identify learning-induced alterations in mitral cell activity. In vitro studies of a slice preparation of the olfactory bulb allow us to test biophysical models of mitral cell plasticity. Patch and optical recording methods are utilized to understand the role of oscillatory dynamics and neurogenesis in odor recognition and memory storage. Computational methods generate biophysically-based network models of the olfactory system to identify general design principles. With collaborators in electronic olfaction we work on developing new odor sensor arrays, sensor circuits and algorithms to develop a new generation of electronic olfactory systems able to solve hard problems like finding buried land mines or contribute to disease diagnosis.
