Dr. JoAnn Difede is currently serving as the lead PI of a large multi-site Department of Defense funded clinical trial contract entitled, "Enhancing Exposure Therapy for PTSD: Virtual Reality and Imaginal Exposure with a Cognitive Enhancer," which is investigating how the use of virtual reality and the pharmacologic agent, D-Cycloserine, may help accelerate recovery from combat-related PTSD among U.S. service members deployed to Iraq and Afghanistan. Dr. Difede has served as the PI of several NIH-funded treatment studies concerning the development of innovative treatments for PTSD. She is also the recipient of many grants and corporate medical contracts for projects concerning the delivery of optimal care for trauma survivors and their families, both from private foundations and publicly held Fortune 500 corporations. Her treatment research spans survivors of burn injuries, terrorism, and occupations at-risk for PTSD, including U.S. soldiers deployed to OIF/OEF/OND, firefighters, police officers, and disaster rescue and recovery workers.

Dr. Difede has advised many corporations, non-profit organizations, and governmental agencies in the U.S. and internationally regarding the implementation of best practices for the screening, evaluation, and treatment of trauma and PTSD. Dr. Difede has served on NIH special emphasis review panels on occupations at-risk for trauma and PTSD and CDMRP review panels, among others. She currently serves on the scientific advisory board of the Anxiety Disorders Association of America (ADAA) and the advisory board of the Jericho Project, a non-profit foundation serving homeless veterans. She recently completed a four-year term on the editorial advisory board of the Journal of Traumatic Stress.

Dr. Difede received the 2010 Award for Outstanding Contributions to the Practice of Trauma Psychology from the American Psychological Association’s Division of Trauma.
