The Morey lab has many talented contributors with strengths in diverse fields including psychiatry, neuroimaging, clinical neuroscience, biomedical engineering, computer science, psychology, as well as cognitive, affective, and social neuroscience.

Principal Investigator

moreyDr. Rajendra Morey is an Associate Professor in the Department of Psychiatry at Duke University School of Medicine, Director of the Neuroimaging Core of the VA Mid-Atlantic Mental Illness, Research, Education, and Clinical Center (MIRECC), staff psychiatrist at the Durham VA Medical Center, and core faculty in the Duke-UNC Brain Imaging and Analysis Center (BIAC).

Dr. Morey received a B.S. in Computer Engineering and an M.S. in Computer Science from Case Western Reserve University, and a M.D. degree from Hahnemann University (now Drexel University) School of Medicine in 1997. After completing residency training in general psychiatry at the University of New Mexico and an NIMH extramural research fellowship at the University of North Carolina at Chapel Hill with Drs. Jeffrey Lieberman and Aysenil Belger, he started at Duke and the Durham VA.

Current research interests include: elucidating how PTSD symptoms alter the balance of prefrontal-limbic signaling during tasks of executive function, emotional distraction, symptom provocation, and memory function, leading to novel insights regarding the neural circuits associated with cognitive and emotional deficits in PTSD; developing a diagnostic approach for TBI using diffusion tensor imaging (DTI) that can be applied at the single subject level; and assessing the merits of competing neuroimaging methodologies for structural MRI morphometry and volumetry.

Dr. Kevin LaBar, Ph.D. is Professor of Psychology and Neuroscience at Duke University. Dr. LaBar’s research emphasis is on the cognitive neuroscience of emotional learning and memory with particular focus on the role of the amygdala and hippocampus in fear-dependent learning. Drs. LaBar and Morey have collaborated for the past 5 years on several fMRI studies of veterans with PTSD, focusing on the imbalance of prefrontal-limbic signaling during tasks of executive function, emotional distraction, symptom provocation, and memory. Dr. Morey has published several manuscripts with Dr. LaBar and is embarking on a new phase of collaboration to determine whether fear generalization in PTSD can come under stimulus control to restore balance in the relevant fronto limbic pathways.

Research Scientists

Dr. Delin Sun, Ph.D. is a research scientist. He received his PhD in BioPhysics in The University of Science and Technology of China, and then worked as a post-doctoral fellow and research assistant professor in the department of psychology in The University of Hong Kong. He is now working on uncovering the neural anatomy and neural functions of Post-Traumatic Stress Disorder (PTSD) and moral injury. He also has great interest in social neuroscience, including face recognition (expression, attractiveness and familiarity), social interaction (dishonesty, cooperation) and affective processing. His research methods include behavioral, neuroimaging (MRI/fMRI) and neurophysiological (EEG/ERP) approaches. Outside of work, he loves spending time with his wife and three kids.

Data Analysts

haswellCourtney Haswell, M.S. is an analyst/programmer at the Duke-UNC Brain Imaging and Analysis Center. She received a B.S. in Biomedical Engineering with a minor in Physics from Virginia Commonwealth University, and a M.S. in Biomedical Engineering from Johns Hopkins University. Her thesis described the acquisition of internal models of motor control in children with autism and was published in Nature Neuroscience. As part of a graduate student medical device design team, her work on a portable negative pressure ventilation device contributed to the development of a novel method of electronically stimulating the phrenic nerve in emergency situations (patent pending). Previous research includes motor learning, autism, spectral analysis of speech signals, and biomechanics. Courtney is a member of Tau Beta Pi Engineering Honor Society. Outside of work, she loves spending time with her three kids, being outdoors hiking and biking, and exercising.

Dr. Adam Fijtman, M.D. Ph.D. is a resident in psychiatry at Duke University Medical Center. Dr. Fijtman received his M.D. and Ph.D. degrees at Universidade Federal do Rio Grande do Sul in Brazil. He has dedicated his research career to studying aspects of cognition, resilience, and trajectory of psychiatric disorders. During his Ph.D., Dr. Fijtman investigated how bipolar disorder affects emotional memory, an essential cognitive aspect associated with amygdala function. His thesis focused explicitly on how childhood trauma and multiple mood episodes affect emotional memory in patients with bipolar disorder. Dr. Fijtman is interested in the impact of exposure to traumatic events and psychiatric diagnoses on cognition in the Veteran population.

Ashley Huggins, Ph.D. (she/her) is a postdoctoral research associate in the Morey lab at the Duke-UNC Brain Imaging and Analysis Center. She received a B.A. in Psychology from the University of Southern California. She completed her M.S. and Ph.D. in Clinical Psychology at the University of Wisconsin-Milwaukee, working under the mentorship of Dr. Christine Larson. She completed her predoctoral internship in neuropsychology at the Charleston Consortium, a collaborative effort of the Medical University of South Carolina and the Ralph H. Johnson VA Medical Center. In her research, Dr. Huggins broadly aims to identify neurobiological mechanisms involved in the etiology and maintenance of trauma-related psychopathology. Her interests largely center on aberrant neural processes relevant to threat regulation, including fear conditioning and generalization, and response to unpredictable threat. She is also especially interested in how broader socio-environmental factors – such as neighborhood disadvantage and exposure to community violence – affect neurodevelopmental trajectories to impact affective and cognitive function. Outside of the lab, she enjoys reading, hiking, and going to see live music.
