Louise Gaston, PhD

Biographical Info Dr. Louise Gaston, PhD, is the founder and director of TRAUMATYS, a clinic specialized in evaluating and treating PTSD. After her doctorate from the University of Montreal, Dr. Louise Gaston completed a 2-year postdoctoral fellowship in the Department of Psychiatry at the University of California in San Francisco (UCSF) with Dr. Mardi Horowitz, author of Stress Response Syndrome, and Dr. Charles Marmar and Dr. Daniel Weiss, ex-presidents of the International Society of Traumatic Stress Studies. At UCSF, Dr. Gaston acquired an expertise in both PTSD and psychotherapy research. Subsequently, she was recruited to become an assistant professor by the Department of Psychiatry at McGill University, where she conducted clinical studies for many years. As a researcher, Dr. Gaston collaborated with many colleagues in diverse settings, including Stanford University and University of Pennsylvania, and carried out clinical trials. Her main research topic was the alliance in psychotherapy and its interaction with techniques, as they contribute to psychotherapeutic efficacy. She has developed the California Psychotherapy Alliance Scale, CALPAS, a measure of the therapeutic alliance which is now used as a standard in clinical research around the world.
