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.

  • Armed conflict/Interpersonal violence
  • Treatment of Military/First Responders
  • Psychedelic-assisted therapy
  • Religiosity/Spirituality
  • The Meaning Crisis/Telos Crisis
