  • The Ressler lab at Yerkes National Primate Research Center is focused on the molecular and cellular mechanisms of fear learning and the process of extinction of fear in mouse models. The primary objective of the work in the Ressler lab is to utilize the power of molecular genetics to understand the molecular biology, the neural circuitry, and the behavioral biology of fear and extinction of fear in mouse models.

  • Dr. Ressler is also a practicing psychiatrist with an interest in translational and clinical research on fear-based psychiatric disorders. During his clinical time, Dr. Ressler is co-director of a newly created Post-traumatic Stress Disorders Clinic at the Adult Outpatient Psychiatry Clinic at Grady Memorial Hospital.

  • We hope that by understanding how fear works in the mammalian brain in the laboratory, it will improve our understanding of and provide translational treatments and possibly prevention for fear-based disorders, such as Post-traumatic Stress Disorder, Phobic Disorders, and Panic Disorder.

The Grady Trauma Project
This project aims to determine the relative contribution of genetic and trauma-related risk factors for Posttraumatic Stress Disorder (PTSD) in a cross-sectional study of a highly traumatized, low socioeconomic status, minority urban population.
