Research Interests:

The primary focus of my research is to understand the cellular and molecular mechanisms of developmental neuropsychiatric disorders such as depression and PTSD. To investigate the nonsynaptic and synaptic plasticity in the brain under both normal and pathological conditions, we use a combination of techniques in the lab:

1) Physiological and pharmacological approaches include whole-cell or cell-attached patch-clamp recordings (with or without In vivo drug administration via cannulation) at the soma or dendrite, and extracellular field potential recordings. 2) Morphological approaches include single-cell labeling, immunocytochemistry, and neuronal reconstruction. 3) Molecular approaches include viral-mediated gene delivery (e.g., overexpression and knockdown), western blotting, immunohistochemistry, and single-cell RT-PCR. 4) Behavioral approaches include open field test, elevated plus maze test, light/dark box test, sucrose preference test, and forced swim test. 5) We use chronic stress or acute stress to generate an animal model of depression or PTSD. These multidisciplinary approaches enable us to conduct research projects associated with developmental neuropsychiatry disorders such as depression and PTSD.
