Tonya Van Deinse is a research associate professor at the University of North Carolina at Chapel Hill School of Social Work. Dr. Van Deinse and her research team, the Health Interventions in the Criminal Legal System Lab, focus on the development, implementation, and evaluation of complex and inter-organizational interventions that span systems, particularly the behavioral health and criminal legal systems. Dr. Van Deinse started her work in mental health more than 20 years ago in private residential treatment with adults with severe mental illnesses and then later worked in the public mental health system where she began to focus on people with severe mental illnesses in the criminal justice system. Today, Dr. Van Deinse uses implementation science methods to design, implement, and evaluate programs at the interface of behavioral health and legal systems.
