Sam joined after 12 years working as a Lecturer and Reader at Liverpool John Moores University. His specialty is exercise metabolism, focusing particularly on the mechanisms governing carbohydrate and fat metabolism and how exercise and nutrition can be manipulated to improve both health and performance outcomes. To date, he has published more than 60 peer-reviewed research articles and supervised 12 PhD students to completion. Sam is also a sports nutritionist and keen triathlete himself, having completed 8x IRONMAN® races since 2018, including the World Champs in Kona, Hawaii, in 2022.

Hunter works as a kidney doctor in Nashville, Tennessee at Vanderbilt University Medical Center. Though he grew up and completed Medical School in Tennessee, his professional training and experience took him to Salt Lake City, Utah, Pittsburgh and Pennsylvania before coming back home to the Southeast US.

Hunter credits his parents for his interest in triathlon, as they both competed when he was growing up. He’s since raced in a number of multisport races, from sprint to full-distance. Combining his passion for endurance sport with his professional medical experience has created the unique opportunity to dive into the physiology of human fluid and electrolyte balance in both a clinical and performance context.

Lindsey joined PF&H all the way from warm and sunny Sydney, Australia, to develop and manage the new Precision Performance Lab. He has almost 8 years of experience researching thermal physiology using a state-of-the-art environmental chamber in the Heat and Health Research Centre at the University of Sydney where he completed his MSc by research and PhD in Environmental Physiology (all things heat and hydration).

You’ll most likely find Lindsey in the fancy new lab helping athletes dial in their capacity to perform in temperate and hot environments, or out on the local champagne gravel roads of the New Forest here in Dorset.

Chris leverages his passion for endurance sports and his MSc in Sport and Exercise Physiology to provide athletes with personalised fueling & hydration strategies grounded in the latest science.

He was the second guy called 'Chris' on the payroll, so quickly became known as "Minty" after our Lemon & Mint PF 30 Chew. Because the other Chris was "Original-flavour Chris". (Not all nicknames have a good backstory, ok! 🤷‍)

He’s a competitive triathlete himself and formerly worked as an Exercise Physiologist for several sports’ National Governing Bodies.

Emily has a first class BSc (Honours) degree in Sport and Exercise Science from the University of Bath. She first joined the team as an intern during her studies, but wasn't allowed to leave unless she promised to come back full time once she graduated.

Originally from a team sport background, Emily has played football from the age of six, most recently for Bath in the top university league.

Emily works closely with elite athletes across a range of sports to help them dial in their fuel and hydration strategies. She was instrumental in developing our Case Studies database.

While studying Sport and Exercise Science at the University of Birmingham, Tash accumulated first-hand research experience as one of the ‘lab rats’. She continued on with a master’s program where she focused on endurance fueling and carbohydrate metabolism.

Tash's first paper: Personalised carbohydrate feeding during exercise based on exogenous glucose oxidation: a proof-of-concept study was published in the BMC Performance Nutrition Journal in April 2025.

As a competitive triathlete herself, Tash’s passion for fuel and hydration developed through experimenting with strategies during training and racing to maximise her own performance. She thoroughly enjoys staying up to date with the latest research and participating in energy-sapping exercise trials with PF&H to progress the team’s resources and expertise.
