Research
I am interested in understanding the neural mechanisms underlying typical behaviors, and how deficits in such mechanisms lead to neuropsychiatric disorders. Thus far, I have used an integrative molecular, cellular, electrophysiological and behavioral approach to identify mechanisms mediating natural behaviors in healthy animals as well as in disease animal models.
My lab focuses on identifying the cellular and electrophysiological mechanisms mediating experience-dependent brain plasticity in mice. We use cellular tools, in vivo and ex vivo electrophysiological recordings, electroencephalogram recordings, optogenetic and chemogenetic tools, and RNAi technology to understand brain functions in ethologically-relevant behaviors as well as behavioral paradigms that aim to test specific sensory modality, of both healthy mice and mouse models of neuropsychiatric disorders.
My long-term research vision is to focus on ethologically-relevant models and behavioral neuroscience approaches to root systems and cellular neuroscience knowledge for tackling long-standing mechanistic questions about animal behavior. I am particularly interested in establishing non-traditional models. Modern neuroscience has narrowed its focus on a handful of animal models, with a pursuit towards medical neuroscience. I believe we can further our knowledge by using diverse animal models which have all solved the social cognition problem in their own native environments.
