Dr. Morey is Associate Professor of Psychiatry at Duke University and Director of the Neuroimaging Core at the Durham VA Medical Center. He is a clinician-scientist motivated by a keen interest in understanding structural and functional brain changes associated with neuropsychiatric disorders, as well as their environmental and genetic modulators. In the area of PTSD, he uses functional MRI to elucidate how PTSD symptoms alter the balance of prefrontal-limbic signaling during tasks of executive function, emotion distraction, symptom provocation, and memory. He has conducted several methodological studies with MRI examining morphometry and volumetry in the medial temporal lobe and subcortical structures to help guide investigators in selecting brain segmentation strategies. His is focused on investigating promising genetic modulators of brain dysfunction in PTSD. He co- leads the PTSD Neuroimaging Working Group in the PGC and ENIGMA where he has formulated a blue print to identify replicable genetic associations and new insights into the biological underpinnings of PTSD at a scope that is unprecedented in the field of traumatic stress. These efforts have triggered a renewed impetus and a sharpened focus on investigating structural and functional brain differences, their genetic determinants, environmental modulators, and investigating the genetic vulnerability to the effects of trauma and the onset of PTSD.
