Aaron Lyon , Ph.D.
Associate Professor, Department of Psychiatry and Behavioral Sciences

  • Aaron R. Lyon, Ph.D. is an Associate Professor in the Department of Psychiatry and Behavioral Sciences at the University of Washington (UW). He is also Director of the UW School Mental Health Assessment, Research, and Training (SMART) Center, an implementation research and technical assistance center focused on supporting the use of evidence-based behavioral health practices in the education sector. Dr. Lyon’s research focuses on increasing the accessibility, efficiency, and effectiveness of interventions for children, adolescents, and families; delivered within contexts (e.g., schools) that routinely provide care to chronically underserved populations (e.g., low socioeconomic status and ethnic minority youth). He is particularly interested in (1) the identification and implementation of low-cost, high-yield practices – such as the use of measurement-based care – to reduce the gap between typical and optimal practice in low-resource service contexts; (2) methods of promoting flexible and effective implementation of evidence-based psychosocial interventions for youth and families; and (3) development and adaptation of health-information technologies for use by community-based mental health practitioners. Dr. Lyon is currently Principal Investigator on grants from the National Institute of Mental Health, National Institute of Justice, Institute of Education Sciences and various local and national foundations in the United States.
