Nicholas Livingston


Dr. Livingston received his Bachelors in Psychology and Drug and Alcohol Use Counseling from the University of Utah, then his Masters and Doctorate in Clinical Psychology from the University of Montana. Dr. Livingston completed his predoctoral internship at the VA Boston Healthcare System, including rotations in the outpatient Alcohol and Drug Treatment Program (ADTP), Substance Abuse Residential Rehabilitation Treatment Program (SARRTP), and Women’s Trauma Recovery Program (WTRP). Dr. Livingston subsequently completed the 2-year VA Interprofessional Advanced Fellowship in Addiction Treatment (postdoctoral research fellowship) at VA Boston Healthcare System, which included rotations in substance use and posttraumatic stress disorder (PTSD) treatment at VA Boston and VA Brockton Medical Centers. Dr. Livingston is currently a Research Psychologist in the National Center for PTSD, Behavioral Science Division, and an Assistant Professor in the Department of Psychiatry at Chobanian and Avedisian School of Medicine.

Dr. Livingston maintains several active lines of research. Primary foci of his current program include:
1) studies on the co-occurrence of trauma/PTSD and substance use disorder
2) development and evaluation of mobile and web-based interventions for substance use and PTSD (e.g., VetChange)
3) examinations of mental health disparities, healthcare needs, and the effects of minority stress on health among lesbian, gay, bisexual, and transgender (LGBT) individuals.

Dr. Livingston is also actively involved in research to examine the longitudinal course of trauma exposure, discrimination, and mental health using diverse data collection methods (e.g., ecological momentary assessment) and novel assessment strategies.
