T.e.a.r group


Texas Exposure and Anxiety Research (TEAR) Group is coordinated by Dr. Greg Muller in the Department of Psychiatry at the University of Texas at Austin.

We study how evidence-based psychotherapeutic interventions can be disseminated and implemented for people with OCD, anxiety, and trauma disorders.



Topics of interest for our group include:

Primary
  • OCD - Anxiety - Trauma-related disorders
  • Exposure-based therapeutic interventions (e.g., ERP/PE/WET)
  • Implementation of trauma interventions in conflict zones​
  • Armed conflict/Interpersonal violence
  • Treatment of Military/First Responders
  • Psychedelic-assisted therapy
  • Religiosity/Spirituality
  • The Meaning Crisis/Telos Crisis

Secondary
  • ​Artificial intelligence - Ethics/privacy
  • Artificial intelligence - Healthcare settings/patient care
  • Neuromodulation (e.g., TMS/DBS)​​

Collaborations:

•In partnership with Liberzon Lab at Texas A&M University, we are working on a five-year D43 Fogarty Center/NIMH sponsored project:
