Evan Stevens
Evan StevensMSc in Nutritional Science
“Evan is a former age-class short track speedskating national champion and varsity track and field champion, excelling in middle distance events. He holds his masters degree in Nutrition and Nutraceutical science, specializing in ageing and the budding philosophy of lifestyle medicine. he is currently working on ways to increase scientific literacy in the general public and how to interpret claims made in the pop media.”

Julia C. Basso
Julia C. BassoPhD, CYT
“Julia C. Basso, PhD is a post-doctoral research fellow in the Suzuki Laboratory (www.suzukilab.com) at the Center for Neural Science at New York University. As a neuroscientist and dancer, she is interested in the body’s ability to shape the brain. During her graduate years at Rutgers University, under the mentorship of Dr. Joan I. Morrell, she discovered that distinct regions within the reward circuitry of the brain help regulate the motivation for voluntary wheel running in the rodent. For her post-doctoral work, she is studying how exercise affects learning, memory, cognition, and mood from a behavioral, electrophysiological, and genetic perspective in humans. Collectively, this work is beginning to reveal that exercise has a bi-directional relationship on the brain. Future research interests lie in understanding the cellular and molecular mechanisms underlying the cognitive benefits of exercise on the brain. Additionally, she is interested in exploring the mechanisms supporting exercise amotivation, why certain individuals are more inclined to exercise than others, and how we can get people more motivated to engage in this healthy behavior.”

Virginia Davies
Virginia DaviesCo-Founder of FastTwitchGrandma
“FastTwitchGrandma was founded by Virginia Davies who took up sprinting in her fifties along with personal trainer Grayson Fertig. Virginia came to the realization that while she considered herself to be active and healthy, she wasn’t sure if she had the ability to run around and play with her grandchildren. She started researching high intensity training (or sprint training) and became passionate about the benefits of this type of exercise. The initiative “FastTwitchGrandma” was developed in order to start the conversation of the benefits of this type of training (particularly in aging adults).
Dr. Sarah West
Dr. Sarah West PhD, RKin, Assistant Professor, Kinesiology Trent University
“Dr. Sarah West is an Assistant Professor of Kinesiology at Trent University in Peterborough Ontario, and an Adjunct Scientist at The Hospital for Sick Children in Toronto Ontario. Her research interests include examining exercise and bone health in various populations (both pediatric and adult), including in those with chronic disease. She is very excited to be part of the Fast Twitch Grandma group and initiative.”
