Biography

Dr. Livingston is a PI within the VA’s Behavioral Science Division of the National Center for PTSD, a staff psychologist at VA Boston Healthcare System’s Alcohol and Drug Treatment Program, and an Associate Professor of Psychiatry at the Chobanian and Avedisian School of Medicine. His research focuses on complementary areas of substance use disorder (SUD) and posttraumatic stress disorder (PTSD) comorbidity, treatment access and outcomes, and predicting and preventing adverse events (e.g., overdose death, suicide). Dr. Livingston also studies the disproportionate risk of suicide, overdose and alcohol-attributable death among vulnerable veteran populations. He is a thought leader on the subject of mental health disparities among LGBTQ+ individuals and veterans, in particular.

He has received funding to support examinations of the impacts of federal policy changes governing medication for opioid use disorder (MOUD) on access to care, treatment retention, and patient outcomes (PCORI LTF-2024C2-39670 & COVID-2020C2-11081; PI: Livingston); the long-term impacts of combat and other traumas among OEF/OIF/OND veterans (W81XWH-22-S-TBIPH2; PIs: Marx & Bovin); and various studies focused on VA health services and patient outcomes. His current research priorities include improving access to patient-centered SUD and PTSD treatment, deriving mortality phenotypes and modeling risk of death among veterans, and leveraging large language modeling and AI to identify novel markers of risk using electronic medical record data.

Dr. Livingston is a mentor on numerous early career development awards (e.g., K, VA CDA-2) and is core training faculty for the Boston University NIMH T32, VA Medical Informatics Fellowship, VA Interprofessional Advanced Fellowship in Addiction Treatment, and other psychology training programs at VA Boston Healthcare System.
