Expert Panel Members

Annually, GSSI invites subject matter experts to serve on an Expert Panel. The members below represent the 2021 Expert Panel.

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.

Amy Bender, PhD

Director of Clinical Sleep Science at Cerebra Medical and an Adjunct Assistant Professor of Kinesiology at the University of Calgary

Dr. Bender started in the sleep field over 14 years ago as a sleep technologist/RPSGT working at a clinical sleep disorders centre and a world-renowned sleep research laboratory at Washington State University, Sleep and Performance Research Center. She then received her master’s and PhD degrees in Experimental Psychology from Washington State University where she specialized in interindividual responses to sleep deprivation studying the sleep EEG. Dr. Bender then came to Canada for a Mitacs postdoctoral fellowship at the Faculty of Kinesiology at the University of Calgary which was ranked the #1 sport science school in North America. During her work as a postdoc, she helped develop the only validated sleep screening tool for athletes and implemented sleep optimization strategies for numerous Canadian Olympic and professional teams. She won the 2017 Mitacs National award for product commercialization and was selected as one of Mitacs next 150 innovators. After her postdoc, Dr. Bender was the leader of Research and Outcomes at Calgary Counselling Centre where she managed a team of 10 research analysts/assistants, students, and volunteers with an interest in how sleep and exercise interventions could improve mental health. Her current research focus at Cerebra Medical is to help people sleep better by improving sleep disorder treatments with more precise digital sleep metrics. She is passionate about translating sleep science for others to understand and take action with interviews on over 30 podcasts, numerous community and conference presentations, and 14 peer-reviewed publications. She was a former college basketball hall of fame athlete, completed an Ironman in 2009, and currently chases her 3 young kids around.

Diet and the Microbiome in Athletes

Brendan Egan, PhD

Associate Professor of Sport and Exercise Physiology, Deputy Head of School, in the School of Health and Human Performance at Dublin City University, Ireland, Visiting Research Scientist at the Florida Institute for Human and Machine Cognition, USA.


Dr. Egan's research group investigates skeletal muscle function and adaptation across the life course, with special interest in the synergy between nutrition and exercise interventions to optimise performance in athletes and older adults. His recent work has centred on the effect of exogenous ketone supplements on exercise metabolism and running performance. He also practices as a performance nutritionist with athletes across a range of sports, most recently with the Dublin Hurlers and the Irish Paratriathlon team.

Ketones for athletes – current status and future directions

David Kennedy, PhD

Professor of Biological Psychology and the Director of the Brain, Performance and Nutrition Research Centre at Northumbria University in Newcastle, UK


Dr. Kennedy's PhD investigated the cognitive effects of herbal extracts. Since that time he has been involved in the supervision of over 120 controlled trials investigating the effects of nutritional interventions on brain function and performance, which have resulted in over 100 peer-reviewed publications. His research interests include assessing the effects of vitamins and minerals, omega-3 fatty acids, amino acids, and a host of plant-derived extracts and compounds, including polyphenols and caffeine, on human brain function. David, along with colleagues, has also developed commercially available cognitive assessment software and, more recently, a smartphone app for testing cognitive function and mood outside of the laboratory.  He has written extensively on the relationship between nutrition and nutritional interventions on brain function, including his single author book “Plants and the Human Brain” (Oxford University Press), which describes the psychopharmacology of a multitude of plant-derived compounds and how these properties relate to the ecological ‘secondary metabolite’ roles of plant chemicals.

Women Athletes: Fit for Purpose Functional Ingredients

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.

Gareth Wallis, PhD

Associate Professor (Reader) in Exercise Metabolism and Nutrition and the Head of Research and Knowledge Transfer within the School of Sport, Exercise and Rehabilitation Sciences at the University of Birmingham, UK


Dr. Wallis received his PhD in Exercise Metabolism and Nutrition from the University of Birmingham, UK in 2006 and undertook his Postdoctoral training in Integrative Biology at the University of California-Berkley from 2006-2008. Dr Wallis then worked in New Product Research at GlaxoSmithKline, within a scientific program developing new nutritional products and health claims. He started at the University of Birmingham in 2012, where he now conducts academic research in exercise science with a major focus on nutrition and metabolism.  His goal is to better understand how nutrition can be manipulated to enhance metabolic or adaptive responses to exercise, with a particular focus on macronutrients and their roles in performance, training adaptation and health. To study these areas he utilises a range of experimental approaches that enable detailed profiling of metabolic responses to exercise and nutrition intervention in humans. His research and approaches adopted aim to generate the translational knowledge needed for practical application within sport, exercise and health nutrition settings.
