Dr. Evan M. Lowder is an Assistant Professor of Criminology, Law and Society at George Mason University and directs the Early Justice Strategies lab. She received her Ph.D. in Psychology from North Carolina State University. Her research is focused on strategies to reduce offending and improve behavioral health outcomes among justice-involved adults. Specific emphases include adults with serious mental illnesses and substance use disorders, pre-booking and court-based diversion programs, opioid use, and risk and needs assessment. More recently, her work has focused on evaluating the success of pretrial reform efforts, including pretrial risk assessment and pretrial supervision. Dr. Lowder has received funding from local (Fairfax County), state (Indiana Office of Court Services; Indiana Family and Social Services Administration), and federal agencies (National Institute of Justice) to evaluate early intervention strategies that connect justice-involved individuals to community-based treatment, facilitate release from pretrial detention, and improve community outcomes. Her research has been published in outlets such as Justice Quarterly, the Journal of Criminal Justice, Law and Human Behavior, Criminal Justice and Behavior, and the American Journal of Public Health. Currently, Dr. Lowder is a co-investigator on a MacArthur Foundation grant to study pretrial defendants' risks and needs during the pretrial period. Her work has been recognized by the American Public Health Association and the American Psychology-Law Society. She was the 2019 recipient of the Christopher Webster Early Career Award from the International Association of Forensic Mental Health Services. In 2023, she received a Faculty Excellence in Research award from George Mason University President Gregory Washington.
