Personal profile

Research interests

Javier joined the Department for Health at the University of Bath in 2014 as a Lecturer (Assistant Professor) in Human Physiology before being promoted to Senior Lecturer (Associate Professor) in 2017.

Javier's research seeks to understand the interactions between nutrition and exercise in the context of health and disease. One strand of this work is to explore the role of carbohydrate availability in the regulation of energy balance, metabolic health and 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 40 peer-reviewed articles and book chapters in journals such as Diabetes CareObesity ReviewsAmerican Journal of Physiology - Endocrinology and Metabolism and the American Journal of Clinical Nutrition. He also has editorial roles with NutrientsBMC Sports Science, Medicine and Rehabilitation and the International Rugby Board Science Network, and has acted as an expert panel member for the Research Council of Norway and a grant reviewer for the BBSRC and Diabetes UK. Furthermore, Javier is the University of Bath ambassador for The Nutrition Society and The Physiological Society.

After completing a BSc (Hons) in Sport and Exercise Science and an MRes in Exercise Physiology, Javier completed his PhD in 2013, which covered the areas of human nutrition, exercise metabolism, and appetite. Following this, he completed a post-doc in collaboration with the University of Maastricht and Newcastle University studying the effects of nutrition on liver and muscle metabolism.

In addition to academic work, Javier has also provided nutrition consultancy to athletes and businesses.
