Javier is a Human Physiologist based in the Department for Health at the University of Bath. He is also the Lead Performance Nutritionist for Team INEOS cycling team. Javier’s research is aimed at understanding diet-exercise interactions in health and disease. One strand of this work is to explore the role of carbohydrate availability in metabolic health, energy balance and (endurance) sports performance. A second strand aims to uncover new dietary approaches to influence the production of hormones from the gut, and thereby regulate appetite and energy expenditure. Javier has published more than 75 peer-reviewed articles in addition to some book chapters. In recognition of this work, he received the Julie Wallace Award 2018 by the Nutrition Society. He also has editorial roles with The Journal of Physiology and International Journal of Sport Nutrition & Exercise Metabolism. Prior to his lectureship at Bath, Javier completed a BSc (Hons) in Sport and Exercise Science, an MRes in Exercise Physiology, and a PhD in Human Nutrition and Exercise Metabolism. Following this, he completed a post-doctoral fellowship in collaboration with the University of Maastricht and Newcastle University studying the effects of nutrition on liver and muscle metabolism.
