Background

Justin joined ARU in 2014, and is a Professor of Nutritional Physiology within our Cambridge Centre for Sport and Exercise Sciences. He is a Registered Nutritionist with the British Association for Nutrition and Lifestyle Medicine (BANT) and the Complementary and Natural Healthcare Council (CNHC).

With over 25 years’ experience in sport and exercise physiology and nutrition, Justin has worked at various institutions including the British Olympic Medical Centre (London), Brunel University (where he completed his PhD), Victoria University (Melbourne) and the University of Hertfordshire.

He currently holds a Professorship research post at ARU, and additionally is the Senior Team Lead for Muscle, Performance and Recovery platforms at Danone Nutricia Research (Utrecht, NL), within the Nutritional Physiology and Functional Nutrients department, Medical and Nutritional Sciences.

Justin's research focuses on applied nutritional physiology, exploring dietary and nutrient strategies to support exercise training and recovery, muscular adaptations (pertinent to physical development and sarcopenia) and cardio-metabolic health.

His current research interests explore ‘calorie- restriction-mimetic’ and polyphenol phytonutrients on physiological mechanisms associated with fat oxidation and cardio-metabolic health; as well as nutrition factors aligned with the ‘gut-muscle axis’, in particular probiotic and protein interventions to support muscle recovery and adaptations to exercise.

Research interests

  • Effectiveness of phytonutrient polyphenols on fat oxidation, metabolic flexibility and exercise performance
  • Influence of phytonutrient polyphenols on exercise-associated inflammation, oxidative stress and acute recovery
  • Use of intermittent fasting and moderate protein-ketogenic diets on fat oxidation, metabolic flexibility and exercise adherence
  • Assessing the benefits of plant-based proteins on muscle strength, exercise recovery and adaptive gains
  • Impact of probiotic-phytonutrient complexes on gut-muscle axis and metabolic adaptations to exercise
  • Nutritional strategies to minimise gastrointestinal issues associated with aerobic exercise.
