Our primary research interest is to identify the mechanisms that regulate neural circuit organization and function at distinct stages of adult neurogenesis, and to understand how circuit-level information-processing properties are remodeled by the integration of new neurons into existing circuits and how disregulation of this process may contribute to various neurological and mental disorders. Our long-range goals are to translate general principles governing neural network function into directions relevant for understanding neurological and psychiatric diseases. We are addressing these questions using a combination of cutting-edge technologies and approaches, including optogenetics, high-resolution microscopy, in vitro and in vivo electrophysiology, genetic lineage tracing and molecular biology.
