Research Interest:

I am interested in studying the neural circuit and neuromodulatory mechanisms that govern cognitive-sensory behaviors, which underlie neuropsychiatric disease. My thesis research focuses on perceptual decision-making, which underlies our basic capabilities to respond to the environment with appropriate actions and is dysfunctional in multiple diseases such as Parkinson’s and schizophrenia. Using in vivo calcium imaging, optogenetics, and other systems neuroscience techniques, I explored dopaminergic and striatal neural circuit function in auditory discrimination. My data indicates that dopamine regulates striatal sub-compartments for auditory discrimination. Furthermore, dopamine modulates auditory neural representation and neuronal learning within the posterior auditory striatum. Using patient-level data, I am additionally interested in using quantitative techniques to understand brain disorders at behavioral and epidemiological levels.
