Expert Panel Members

Annually, GSSI invites subject matter experts to serve on an Expert Panel. The members below represent the 2022 Expert Panel.

Lawrence Spriet, PhD - GSSI XP Chair

University of Guelph, Ontario, Canada


Dr. Lawrence Spriet is a professor at the University of Guelph in Canada. His research examines how skeletal muscle generates the large amounts of energy needed to exercise and perform in work and sport situations.
Lawrence is recognized as one of the leaders in the field of exercise metabolism and has published extensively on this topic. In addition to his fundamental research, his applied research examines whether compounds that are purported to be “ergogenic” or “work enhancing” agents actually augment muscle metabolism and/or improve human performance. He also conducts hydration/sweat testing and research aimed at counteracting the effects of dehydration in athletes engaging in stop-and-go sports like ice hockey, basketball and soccer. Dr. Spriet has had a long history with GSSI, first coming on board in 1990, helping establish the Canadian GSSI Branch in 2005 and acting as Chair of XP since 2012.

Cheryl Cooky is a professor of American Studies and Women’s, Gender, and Sexuality Studies at Purdue University in West Lafayette, IN. Her research focuses on three areas: gendered media representations of sport; gender politics of sport and public policies; and how gender shapes sports experiences, cultural meanings, and organizational structures in sports. She is the co-author of Serving Equality: Feminism, Media and Women’s Sports (2022, Peter Lang Publishers) No Slam Dunk: Gender, Sport and the Unevenness of Social Change (2018, Rutgers University Press). Her research is published in a diverse array of journals including Journal of Sex Research, Sex Roles, Gender and Society, American Journal of Bioethics, Sociology of Sport Journal, among others. Committed to making research accessible to general audiences, Dr. Cooky has authored opinion-editorial articles, appeared as an expert in several documentary films, television and radio programs, and has been quoted in over 100 national and international news media outlets including The New York Times, The Atlantic, ESPN, Sports Illustrated, The Washington Post, Forbes, Globe & Mail, The Guardian, National Public Radio, among others. She is a past-president of the North American Society for the Sociology of Sport and Editor of Sociology of Sport Journal, the flagship journal of the field.

Martin Gibala, PhD

McMaster University, Hamilton, Ontario, Canada


Dr. Martin Gibala is a professor and the Faculty of Science Research Chair in Integrative Exercise Physiology at McMaster University. His research examines the mechanistic basis of exercise responses in humans, and associated health impacts. Dr. Gibala’s science communication efforts include a bestselling book on the topic of time-efficient exercise, The One-Minute Workout: Science Shows a Way to Get Fit That’s Smarter, Faster, Shorter. He also co-teaches a massive open online course, Hacking Exercise For Health. The surprising new science of fitness. Developed with McMaster colleagues, the course content can be accessed for free through the Coursera learning platform.

Update on high-intensity interval training for athletes and health and wellness

Peter Peeling, PhD

University of Western Australia, Perth, Australia


Peter received his PhD from the University of Western Australia (UWA), where he investigated the impact of exercise on various mechanisms associated to iron deficiency in endurance athletes. This work highlighted the influence of exercise-induced inflammation on the transient increase of the hormone, hepcidin, which plays a regulatory role in controlling dietary iron absorption in the gut. Since this time, Peter has continued to explore the impact of exercise on iron metabolism, with a focus on practical strategies that can optimise iron stores in active populations. In addition to his research interests, Peter has also worked as an applied sports physiologist in the Australian National Institute Network, where he provided sports science services in the daily training environment of many Western Australian athletes competing at a National and International level across multiple 4-year Olympic cycles. As Peter’s role in the NIN has progressed, he now finds himself as the Director of Research at the Western Australian Institute of Sport (WAIS), where he oversees the WA High Performance Sport Research Centre. This centre is a collaborative principal partnership between UWA and WAIS, providing evidence-based, innovative solutions to performance-driven questions, through practical and applied research, which can be translated into an athlete’s daily training environment to optimise current practice or performance. Finally, Peter holds a teaching and research role at the University of Western Australia, in the School of Human Sciences, where he teaches courses in general health and fitness, and applied sports physiology. In this role, Peter also supervises several graduate research students in areas relevant to iron metabolism; training methodologies for enhanced athlete adaptation; and the efficacy of various ergogenic aids on athletic performance.

Kevin D Tipton, PhD

The Gatorade Sports Science Institute pays respect to Professor Kevin Tipton, who sadly passed away on January 9, 2022. Kevin Tipton was a Professor of Nutrition and Exercise Metabolism.

Professor Kevin Tipton, “Kev”, was a great scientist. His contribution to the field of sports nutrition and protein metabolism will live on long after his passing. Not only through his contribution to science but through the huge positive influence he had on the many students he taught and the many professionals he mentored.

His research focused on nutrition and exercise metabolism with emphasis on protein nutrition and metabolism in athletes, healthy volunteers and clinical populations. Kevin authored over 100 papers, book chapters and review articles. He served as an Associate Editor for Applied Physiology, Nutrition and Metabolism and served on the Editorial Board of the International Journal of Sports Nutrition and Exercise Metabolism. He also served on the National Academy of Science’s, Institute of Medicine, Committee for Military Nutrition Research. Kevin also contributed to sports nutrition consensus statements for the IOC, FIFA, FINA and IAAF and also served on the UK Sport Nutritional Supplements Advisory Board. Most recently, Kevin was a Professor at Durham University in the U.K, whilst also consulting with the Institute of Performance Nutrition. Beyond academia, Kevin coached and served as fitness and nutrition advisor for amateur soccer clubs. However, it would be amiss not to mention his passion for all things Rugby. A sport which he played, supported and loved. 

Kevin delivered invited presentations at numerous international conferences on topics related to exercise, nutrition and health. For those who had the pleasure of meeting him, you would know he always had time for people, for debate, for advice, for e-mails as well as social media communications. Kevin was a friend of GSSI. He contributed to many GSSI education and conference events. His review in Sports Medicine, “Nutritional Support for Exercise-Induced Injuries” which he wrote as a GSSI XP member, has had over 25,000 reads, and remains the “go-to” review on the topic.

The picture is one of Kevin walking in the hills of his adopted Scotland, with his beloved dog, Reiver. Thank you Kev. Rest in peace. You will be missed.
