I initially received an MD and a PhD from the University of Toulouse (France). I am a Professor of Psychiatry at the University of Caen Normandy (France), and adjunct investigator at the Massachusetts General Hospital (Boston, MA) where I served in different leadership capacities as a Harvard Medical School faculty, for nearly ten years. My research focuses specifically on understanding the mechanism and improving the treatment of anxiety and stress-related conditions, including using psychopharmacotherapy and mind-body approaches. To date, I have published over 200 scientific articles and book chapters, and edited two textbooks in the field of anxiety disorders, post-traumatic stress disorder, and prolonged grief disorder. I served as President of the International Society for Traumatic Stress Studies (2020-2021), and currently serve as Associate Editor of the European Journal of Psychotraumatology, and as Editor-in-Chief of the International Journal of Mental Health.
