Dr. Walton is an Associate Professor in the Department of Psychiatry and Addiction Research Center at the University of Michigan. Her research interests include developing and testing the efficacy of interventions for alcohol, drug use and violence in community health care settings, such as the emergency department, primary care, and substance use treatment. Her research focuses on the interrelationship among multiple risk behaviors such as alcohol, illicit drugs, and violence, particularly among traditionally understudied populations such as adolescents, women, and African-Americans. She is the co-principal investigator on a brief alcohol intervention study among underage drinkers presenting to the UM Emergency Department (ED). In addition, she is a co-investigator on studies (funded by NIDA and NIAAA) examining substance use trajectories among youth, brief alcohol and drug interventions among adults in the ED, and integrated violence prevention therapy for patients in substance use treatment. Dr. Walton and colleagues recently completed studies examining brief interventions for alcohol and violence among adolescents presenting to urban EDís, marijuana prevention interventions among youth in primary care settings, and health services interventions among not-in-treatment adults with substance use disorders. Dr. Walton has a Ph.D. in Ecological and Community Psychology from Michigan State University and a M.P.H. in Heath Promotion from San Diego State University.
