Research Interests


My research focuses on epidemiological and genomic approaches to the study of substance use and addiction. I am funded by the National Institute on Drug Abuse (NIDA) to study how genetic and environmental factors work together to shape our liability to use cannabis and become addicted to it. In addition, I am co-PI of the Substance Use Disorders Working Group of the Psychiatric Genomics Consortium (PGC). The goal of our working group is to identify common genetic variants that are related to liability for alcohol, nicotine, cannabis and other drug use disorders, and further to relate these loci (and their aggregate effect) to genetic risk for other psychiatric traits (e.g., personality) and disorders (e.g., depression).
