Jonathan Cantor is an associate policy researcher at the RAND Corporation. His key research interests are in health policies related to obesity, substance use disorder, mental health, pharmaceutical use, and other health behaviors. He uses theoretical frameworks and research methods from health economics, policy analysis, and public health. He is currently leading a team of researchers in developing the Mental health and Addiction Treatment Tracking Repository. It is the first national longitudinal database of licensed substance abuse treatment facilities between the year 1975 and the present and for mental health treatment facilities for the years 2008, 2012, and 2015-present. The substance use disorder data are currently being used to examine the availability of substance use disorder treatment for older adults via a National Institute of Aging grant. Both the mental health and substance use disorder database have been used to examine the availability of specialty behavioral health treatment surrounding army bases and separately for veterans. Cantor has also examined changes in health care utilization, access to care, and health outcomes due to the COVID-19 pandemic. He has published articles in journals including Health Affairs, Journal of Health Economics, New England Journal of Medicine, and American Journal of Public Health.
