Research interests

My research focuses on how increased arterial stiffness affects brain blood flow and how older persons experience dizziness and increased risk of falling. I have studied astronauts to understand how and why arteries have “aging-like” changes (increased carotid artery stiffness) after 6-months in space. My research in the science of human health developed from my own participation in competitive distance running and the belief that physical activity contributes to long and healthy lives. 

Richard Hughson is the Schlegel Research Chair in Vascular Aging and Brain Health and a Fellow of the Canadian Academy of Health Sciences.
