Blaine Hoshizaki

Biography

I am the director of the Neurotrauma Impact Science Laboratory (ADD HYPERLINK https://sites.google.com/site/neurotraumaimpactlab/) at the University of Ottawa. Our research has focused on decreasing the risk of head injuries in sport. We primarily investigate the relationship between the accident event and resulting brain tissue trauma. My role is to lead head injury reconstructive research employing physical event reconstructions and computational modelling.
