Dr. Han earned his PhD in genetics from Fudan University, in Shanghai, China, in 2006. He did his postdoctoral training at Yale, where he started his research on the genetics of substance abuse in the laboratory of Dr. Joel Gelernter, a world leader in this area (2008-2012). Prior to joining Johns Hopkins, he was an Assistant Professor (2012-2017) and then a tenured Associate Professor (2017) in the Department of Psychiatry at the University of Iowa. His research is focused on investigating the genetic basis of psychiatric disorders, especially alcoholism and substance abuse. He is also involved in developing statistical genetic approaches and computational tools that will facilitate the effort to identify disease susceptibility genes more broadly. Dr. Han has been a Principal Investigator on multiple projects funded by the National Institutes of Health and by private foundations.
