James studied for his undergraduate degree (BSc) in Sport and Exercise Science at Loughborough University, graduating in 2007. James’ time at Loughborough then continued as he went on to complete a PhD in Exercise Physiology, focusing 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 obesity-related liver disease.

James is currently a Reader in Clinical Exercise Science 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 disease.

James' research interests focus on the interaction between exercise and diet with energy balance and obesity-related disease.

James is currently undertaking research in the following areas:

  • Exercise as a therapeutic strategy in patients with obesity-related liver disease and type 2 diabetes
  • Drug-lifestyle interaction in the context of obesity-related disease
  • Appetite control, energy balance, obesity and weight management
  • Bespoke workplace interventions targeting risk factors for chronic metabolic disease (e.g. sedentary behaviour, physical inactivity, poor diet)
