Trauma Anxiety and Stress (TAS) Lab

Research Overview

Our research examines the mechanisms underlying the development and treatment of Posttraumatic Stress Disorder (PTSD) and Anxiety Disorders, predictors of response to exposure therapy for anxiety disorders, and the impact of stress and trauma on brain and emotional functioning. Specific research questions include examining the impact of stress and sex hormones, sleep and cognitive processes on emotional memory consolidation (intrusive memories), fear extinction, and treatment response in individuals with anxiety disorders and PTSD.  The aim of this research is to lead to the development of more targeted and effective treatments for PTSD and anxiety disorders.

Current Projects:

  1. The Impact of Exercise on Fear Extinction Learning and memory consolidation
  2. The Effect of Stress and Sex Hormones on Fear Conditioning, Extinction and Reinstatement
  3. The Effect of Stress and Sex Hormones on Emotional Memory Consolidation
  4. Predictors and Mediators of Exposure Therapy Response for Anxiety Disorders
  5. Memory contextualization, intrusive memories and PTSD
  6. The Impact of Acute Stress on Attentional Bias towards Threat
  7. Neurobiology of Trauma and PTSD
  8. TDCS and fear extinction
  9. Type and timing of trauma and Event Related potentials
  10. Adjustment and mental health in refugees
  11. Hair cortisol as a predictor of psychopathology following trauma
