Research Focus

Dr. Peng’s research interest broadly defined is to understand the biological determinants of human behaviors through innovative applications of algorithms and statistics. Specifically, we are currently focusing on dissecting the complex genomic and epigenomic basis of addiction and related behaviors through multi-omics and integrative computational approaches. We are also interested in determining how ancestral background and genetic interactions confer risk or protection for addictive and comorbid mental disorders. Our goal is to provide more precision in the understanding of the mechanism underlying risk for addiction and thus provide a substrate for more effective prevention and intervention.
