Faculty Focus - Alexander Velumian

Alexander Velumian, PhD

Dr. Alexander “Sasha” Velumian graduated from Moscow State University before going on to complete his PhD and DSc at the I.M. Sechenov Institute of Evolutionary Physiology and Biochemistry of the Russian Academy of Science in St. Petersburg. After completing his post-graduate training, he became a Scientist – and later Leading Scientist – at the same institute. He first joined the Toronto Western Research Institute in 1992 as a Research Associate. Dr. Velumian is currently an Assistant Professor in the Departments of Surgery and Physiology at the University of Toronto and a Research Neuroscientist in Division of Neurosurgery at Toronto Western Hospital, working in the spinal cord injury program headed by Dr. Michael Fehlings. His current research focuses on the organization of the living myelin sheath and myelin-axon interactions in CNS white matter, and functional aspects of myelination/demyelination in CNS white matter.
