Primary Appointment in Pathology; Secondary Appointments in Neurology, Neuroscience, Psychiatry
Member, Graduate Program in Neuroscience; Member, Graduate Program in Pathobiology

Vassilis E. Koliatsos, MD, MBA is Professor of Pathology (Neuropathology) and Neurology and Associate Professor of Psychiatry and Behavioral Sciences. His main research interest is neural responses to traumatic and degenerative insults and mechanisms of neural repair and has close to 100 publications in this area. He has characterized a number of nourishing peptide chemicals (“neurotrophic factors”) for key populations of neurons in the brain and his stem cell work in animal models of disease has recently entered the first clinical trial of cellular therapy for a major neurodegenerative disorder (ALS). He has mentored numerous pre- and post-doctoral students and has taught residents in neurology and psychiatry on basic and clinical neurosciences.

Dr. Koliatsos' present emphasis is on Traumatic Brain Injury (TBI), especially the role of axonopathy in mechanisms associated with chronic TBI such as disconnection and its transsynaptic effects, neuroinflammation, and proteinopathy (tauopathy, amyloidosis). In parallel, he does research on the use of stem cells as cellular therapies for TBI. He also explores the use of induced pluripotent stem cells as in vitro models (cell cultures, cerebral organoids) of human neurological and neuropsychiatric illness.

Dr. Koliatsos serves on the faculty of the Ph.D. graduate program of Pathobiology of Disease and has also served in the Ph.D. Neuroscience program. Dr. Koliatsos also leads the Traumatic Brain Injury Research Center in the Department of Pathology and sees patients with traumatic brain injury and degenerative dementias. Dr. Koliatsos has been awarded the Leadership and Excellence in Alzheimer’s disease Award and the Javits Neuroscience Investigator Award, both from NIH.
