Research Interests

Functional neural circuits in the brain involve a network of connected neurons, which process input and output information. The neural activity would be determined by the balance of synaptic excitation and inhibition. Any manipulations that shift the balance will change the output of the circuit. My research goal is to understand how the balance of excitation and inhibition within neuronal circuits is achieved, how it develops with experience, and how it changes in response to exogenous manipulations. I am currently investigating how various neurons interact and integrate chemical sensory information in the olfactory bulb circuits by employing neuroanatomical and neurophysiological approaches in brain slices.
