Igor Smirnov, DVM

Assistant Professor, Pathology & Immunology


  • DVM: Moscow State Academy of Veterinary Medicine and Biotechnology, Moscow, Russian Federation (1986-1993)

Research Interests

My main interest is in developing animal models of traumatic and degenerative injuries of the nervous system to assess the role of the immune system during normal brain function, after an injury, and during the course of a neurodegenerative diseases.
