Gregory Aarons, PhD is a clinical and organizational psychologist, Professor of Psychiatry at UC San Diego, Director of Child and Adolescent Services Research Center (CASRC), and Co-Director for the Center for Organizational Research on Implementation and Leadership (CORIL). His research, funded by the U.S. National Institute of Mental Health and the National Institute on Drug Abuse, and the Centers for Disease Control, focuses on identifying and improving system, organizational, and individual factors that support successful implementation and sustainment of evidence-based practices and quality of care in health care and public sector allied health care settings. With his colleagues, he developed the Exploration, Preparation, Implementation, Sustainment (EPIS) implementation framework. Gregory also developed the Evidence-Based Practice Attitude Scale (EBPAS), and with colleagues has developed measures of implementation leadership, implementation climate, and implementation citizenship behavior. Dr. Aarons’ work focuses organizational change management for implementation that includes: improving organizational context, supports, and processes while concurrently training supervisors to become effective leaders to support evidence-based practice implementation and sustainment. His work also examines the roles of system and policy context and their interactions with organizational context in evidence-based practice sustainment across multiple service systems. Other lines of inquiry involve understanding and improving implementation of evidence-based interventions in low- and middle-income countries.
