Dr. Walsh’s research is focused on investigating the mechanisms by which daily behaviours (physical activity, diet, screen time, sleep and cognitive stimulation) impact brain function. The overarching goal of this research is to apply this knowledge to develop interventions that optimize brain health across the lifespan. Dr. Walsh’s research is particularly interested in characterizing how exercise increases the neuroactive hormone brain-derived neurotrophic factor (BDNF), and investigating the effect of BDNF on brain function. The primary measurement outcomes of this research are: 1) measuring neuroactive hormones in the blood, 2) assessing cognitive function, 3) measuring cerebral blood flow.

Dr. Walsh is currently accepting graduate students for Fall 2021. If you are interested in a research opportunity with Dr. Walsh, please fill out an application here.
