Psychology Graduate Student

Learn more about Kathleen

Kathleen Martin went to the University of Minnesota for her Bachelor of Science degree. In Minnesota, she worked at the Minneapolis VA and the Minnesota Center for Twin and Family Research where she first became acquainted with behavioral genetics. Currently, she is a fourth-year student in the Clinical Psychology PhD program at Emory University and is interested in behavioral genetic contributions of internalizing and externalizing disorders. She is especially interested in genetic and environmental predictors of opioid use/misuse. Her current projects focus on the overlapping genetic and behavioral architecture of mood/anxiety disorders and opioid use behaviors.


Kathleen is actively recruiting undergraduate research assistants to assist in data cleaning and analysis of many large behavioral datasets that have information on these variables. Prior experience with R is required.
