Biographical Sketch

Dr. Ryan is an Assistant Professor in the Department of Psychiatry at The University of Texas Health Science Center at San Antonio (UTHSCSA). She completed her graduate training at Emory University studying the relationship between biological and social factors as predictors of aggressive behavior and response to Multisystemic Therapy. Building on this work, Dr. Ryan completed postdoctoral training in the Center for Addiction Research at the Psychiatric Research Institute of the University of Arkansas for Medical Sciences where she participated in randomized clinical trials that sought to examine how evidence-based treatment modifies the relationship among parent and adolescent risk and protective factors for substance abuse\dependence and externalizing psychopathology. To incorporate biological measures, Dr. Ryan’s training also included neuroimaging techniques of decision making among youth receiving individual and family-based treatments.

Dr. Ryan's primary research interests center on identifying biosocial factors that influence outcomes for treatment of youth substance use disorders and related aggressive/delinquent behavior. She is particularly interested in using this information to understand the utility of current intervention programs. Dr. Ryan hopes that her research will lead to the improvement of current evidence-based treatment programs that are aimed at treating adolescent substance use and other externalizing behaviors
