Kerry J. Ressler received his Bachelor of Science degree in molecular biology from M.I.T., and his M.D./Ph.D. from Harvard Medical School. Dr. Ressler is an Investigator of the Howard Hughes Medical Institute, a Professor of Psychiatry and Behavioral Sciences at Emory University, and a Member of the Institute of Medicine of the National Academy. His work focuses on translational research bridging molecular neurobiology in animal models with human genetic research. His clinical research examines genetic and behavioral processes that underlie Posttraumatic Stress Disorder (PTSD) with the goal of understanding the molecular mechanisms that contribute to fear-related disorders. His basic research is focused on understanding the molecular basis of amygdala function and fear processing using transgenic mouse models.
