Kwang Choi, PhD, is an Assistant Professor of Psychiatry at the Uniformed Services University in Bethesda, Maryland. Dr. Choi received his BS and MA in Biology from the Dongguk University in South Korea, and his Ph.D. in Neuroscience and Psychiatry from the University of Alberta in Edmonton, Canada. He completed a postdoctoral training at the Department of Psychiatry of the University of Texas Southwestern Medical Center at Dallas, TX, and worked as a Scientist at the Stanley Laboratory of Brain Research in Rockville, MD.

The long-term goal of Dr. Choi's research is to better understand the biological mechanisms of stress, anxiety, and substance abuse. He is conducting pre-clinical neuroscience research by utilizing clinically relevant animal models such as fear learning and drug self-administration as well as molecular and cellular assays such as in vivo brain imaging (FDG-PET and CT scan) and RNA sequencing of brain tissue. These approaches complement each other by elucidating the neurobiological mechanisms mediated by biological and environmental factors contributing to vulnerability or resilience to stress and substance abuse. Identifying the mechanisms in which drugs and environment interact and change the brain to lead to psychiatric symptoms, will contribute to the development of improved treatment strategy for substance abuse and anxiety disorders including PTSD.
