Vassilis Koliatsos

Vassilis E. Koliatsos, MD, MBA
email: [email protected]

Vassilis Koliatsos, Professor of Pathology (Neuropathology), Neurology, and Psychiatry and Behavioral Sciences, is the head of the Laboratory. Dr. Koliatsos trained in systems neuroscience with Mahlon DeLong and cellular and molecular neuropathology with Don Price. His main interest is mechanisms of neural injury and repair. He has characterized a number of neurotrophic factors for brain cholinergic and spinal cord motor neurons and initiated experimental therapies of traumatic and degenerative diseases with stem cells and their progenies. In recent years, he turned to the problem of traumatic brain injury, both as morbidity in and of itself and as model for neurodegenerative disorders, with emphasis on white matter injury.  He is on the faculty of the graduate program of Pathobiology of Disease and leads the Brain Trauma and Degeneration Program.  A clinical neuropsychiatrist, he also sees patients with TBI and degenerative dementias. Dr. Koliatsos has received a Javits Neuroscience Investigator Award from NINDS and a 2018 Discovery Award from Johns Hopkins University.

Thanasis Alexandris, the junior faculty member in the group and Research Associate in Pathology (Neuropathology) has a neuropathology background and focuses on common mechanisms underlying neurodegenerative diseases and neural injury, with an emphasis on axonal pathology and Wallerian degeneration. He joined the Koliatsos lab in 2018 as a postdoctoral fellow and became a faculty member in 2023. His primary research interests include SARM1 signaling in models of axonopathy and understanding the mechanisms of collateral axonal plasticity following neurotrauma. His broader interests include axonopathy in demyelinating diseases and human synucleinopathies.
