Active Mentor - currently hosting PULSe students for laboratory rotations and recruiting PULSe students into the laboratory; serves on preliminary exam committees

Current Research Interests:

A major challenge in neuroscience is to understand how brain circuits perform computations, affect perception and behaviors and how these circuits are altered in
diseases such as autism, Alzheimer's Disease and stroke. We use a multi-disciplinary approach: using optogenetics and robotics to map neural circuits in vitro,
electrophysiological recordings and direct neuronal stem cell reprogramming in vivo. We use the mouse visual cortex as a model system, as it combines the ease of
manipulating visual stimulus with accessibility for in vivo recordings in a genetically tractable animal model. This combination of in vitro and in vivo
electrophysiology with the optogenetic and reprogramming tools provides an integrated platform to dissect and manipulate specific circuits relevant for visual
perception, and study diseases affecting perception and neural circuit function, such as autism, Alzheimer's Disease and stroke.
