ǧÃŬAV

Dr. Sun joined Department of Psychological Science at ǧÃŬAV-Dahlonega in the fall of 2020. He has a doctoral degree in Biopsychology and Behavioral Neuroscience from City University of New York. He received his post-doctoral research trainings at University of Chicago, Medical University of South Carolina, and University of South Carolina. His research focuses on the behavioral and molecular changes after exposure to drugs of addiction. He is currently conducting nicotine studies in mice with undergraduate students. He hopes to expand his research into human study, and bring more undergraduate research projects in the future.
