Personal profile
Research Interests
We use imaging approaches to acquire large-scale recordings of neural activity during behavior, focusing on deep-brain areas implicated in neurological and psychiatric diseases, such as striatum. We use these tools to delineate the functional contribution of neuronal sub-populations in these brain areas to normal behavior in control subjects and pathological behavior in models for brain diseases. Our aim is to target these neural substrates to improve treatment outcomes for neuropsychiatric diseases.
