Jeremy Walsh is an Assistant Professor in the Department of Kinesiology at McMaster University. Jeremy completed both his MSc and PhD at Queen’s University before carrying out a Postdoctoral Fellowship at the University of British Columbia. His research is focused on investigating the mechanisms by which daily behaviours (physical activity, diet, screen time, sleep and cognitive stimulation) impact brain function. Jeremy and his research team are particularly interested in characterizing the impacts of these behaviours on the neuroactive hormone brain-derived neurotrophic factor (BDNF), cerebral blood flow and cerebrovascular function, and cognition. The overarching goal of his research is to apply this knowledge to develop interventions that optimize brain health in middle-to-older aged adults.
