Dr. Joseph B. Long is the chief of the Blast-Induced Neurotrauma Branch of the Center for Military Psychiatry and Neuroscience at the Walter Reed Army Institute of Research in Silver Spring, MD. In this capacity, he heads a research team using animal models and biofidelic surrogates to validate and characterize scaled experimental blast exposure conditions and assessments of outcomes relevant to blast-injured warfighters. Their research targets definition of the biomechanical and neurobiological underpinnings of blast TBI, determination of the contributions of operational, environmental, and psychological stressors and nutritional deficiencies to mTBI severity, and establishment of effective countermeasures to improve return to duty and readiness. He received his BSc degree in Biology from the Bucknell University in 1977 and PhD degree in Pharmacology from the University of North Carolina at Chapel Hill School of Medicine in 1982. Prior to becoming a civilian researcher at the Walter Reed Army Institute of Research, he served 7 years of active duty in the US Army.
