Jennifer Heisz


Dr. Jennifer J. Heisz is an expert in brain health. She is Associate Professor in the Department of Kinesiology at McMaster University (ranked Top 25 in the world) and directs the NeuroFit Lab, which has attracted nearly $1 million to support her research program on the effects of exercise for brain health. Dr. Heisz received her Ph.D. in Cognitive Neuroscience (McMaster) and completed a postdoctoral fellowship in Brain Health and Aging at the Rotman Research Institute at Baycrest Hospital (Toronto). Dr. Heisz's research examines the effects of physical activity on brain function to promote mental health and cognition in young adults, older adults and individuals with Alzheimer’s disease. Many honors and awards recognize Dr. Heisz for her outstanding contributions to research including the Early Researcher Award from the Government of Ontario, the Petro-Canada Young Innovator Award.


Michelle Ogrodnik is a doctoral student in the NeuroFit Lab. She also works with Dr. Barbara Fenesi (NeuroFit alumni) at Western University in the WEBB Lab. Combining her knowledge in cognitive psychology, neuroscience, and kinesiology, she is interested in understanding ways to improve attention and long-term comprehension. Currently, she is investigating how physical fitness and exercise participation influence symptoms of inattention in adults with Attention Deficit Hyperactivity Disorder (ADHD). Michelle is an award winning science communicator and enjoys sharing her work with diverse audiences. She is also an award winning teacher, and an advocate for evidence-based and equitable teaching practices. Alongside her research, Michelle works as a Lead Student Educational Developer at the MacPherson Institute for Leadership, Innovation and Excellence in Learning. Her ultimate goal is to combine her program of research and work experience to improve teaching and learning in higher education.

Each year, the NeuroFit Lab trains dozens of top undergraduate students from across the Faculty of Science including Kinesiology, Psychology, and Biology. Bringing together trainees from distinct disciplines into our open workspace in the lab creates an engaging environment for knowledge transfer and innovative thinking. This rich knowledge foundation is complemented with extensive technical training on multiple methodologies—fNIRS, EEG, cognitive and fitness testing, and biological sample processing—and the use of both traditional and novel analytical procedures for data analysis. Trainees from the NeuroFit Lab are equipped with a valuable skill and knowledge set needed to address the challenges of an increasingly sedentary and aging population.
