James studied for his undergraduate degree (BSc) in Sport and Exercise Science at Loughborough University and graduated in 2007. James’ time at Loughborough then continued as he went on to complete a PhD in Exercise Physiology, which focused on the interaction between exercise and the neuroendocrine regulation of appetite & energy balance.

In November 2010, James commenced his post-doctoral research in the Exercise, Inflammation & Metabolism research group at Loughborough, during which time he contributed to the application which brought a National Institute of Health Research (NIHR) Biomedical Research Unit (Diet, Lifestyle & Physical Activity) to the University. During the first three years of this award, James worked as a Senior Research Associate across several research areas relating to exercise and its contribution to the management of chronic metabolic disease, particularly type 2 diabetes and non-alcoholic fatty liver disease.

James is currently a Senior Lecturer in Exercise Physiology within the School of Sport, Exercise & Health Sciences, and his research continues to investigate the role of lifestyle (exercise and diet) in the development and management of obesity and obesity-related diseases.

James' main research interests focus on the interaction between exercise and diet with energy balance, metabolism and chronic metabolic disease.

James is currently undertaking research in the following areas:

  • Exercise as a therapeutic strategy in patients with Non-Alcoholic Fatty Liver Disease (NAFLD)
  • Appetite control, energy balance and obesity
  • Bespoke workplace interventions targeting risk factors for chronic metabolic disease (e.g. sedentary behaviour, physical inactivity, poor diet)
  • High intensity intermittent exercise (HIT), metabolism and cardiometabolic health
