Research Interests
My long-term research goal is to better understand the genetic architecture of psychiatric disorders, particularly focusing on substance use and addictions. Within addictions, I am particularly interested in the study of more commonly used drugs, such as alcohol and cannabis. One current area of research interest is characterizing the relationships between substance use disorders and other psychiatric disorders and mental health conditions, including schizophrenia, suicidal thoughts and behaviors, and chronic pain. A second area of research interest is using approaches from the population and evolutionary genetics fields to learn more about the genetic architecture of psychiatric disorders. I am currently one of the analysts for the Psychiatric Genomics Consortium’s Substance Use Disorders working group and a co-investigator in the Collaborative Study on the Genetics of Alcoholism.
