Research Interests:

Synapses are the fundamental units of neural communication in the brain. Using multidisciplinary approaches, we study how synaptic structure and function are precisely shaped during development and how their dysfunction leads to neurological disorders. By understanding the physio-pathological roles of critical synaptic proteins at the cellular, circuitry and system levels, we aim to identify novel targets and further develop pharmacological and genetic therapies for neurodevelopmental and neurodegenerative diseases.

Our techniques include multi-electrode patch clamp in vitro and in vivo, two-photon imaging, optogenetics, chemogenetics, mouse behavioral analysis, and transgenic mouse models.
