Professor Greaves conducts internationally recognised research on health behaviour change. He develops and evaluates practical interventions to prevent cardiovascular disease and type 2 diabetes and to support self-care by people with chronic illnesses.


Having started life as a chemical engineer and following a brief fling with the construction industry (in industrial flooring), Professor Greaves rejected Mammon and retrained as a health psychologist. He completed a PhD on asthma self-care at the University of Exeter and since then has managed a NHS primary care research consortium and worked for 15 years in the University of Exeter Medical School. Over the course of this work he has helped to develop 11 health care interventions, seven of which (to date) have been subjected to full-scale randomised controlled trials.

Professor Greaves joined the University of Birmingham in January 2018 as a Professorial Research Fellow in the School of Sport, Exercise and Rehabilitation.

Postgraduate supervision

Professor Greaves has supervised to completion seven PhDs and six MSc dissertation projects. He is currently supervising two PhDs and 2 MScs.

Professor Greaves welcomes enquiries from potential new postgraduate students, including self-funded students and those seeking funding for their own project ideas.


Research group: Exercise and Health

Professor Greaves has helped to develop and evaluate intervention programmes to support people in losing weight and reducing disease risk through changes in diet and physical activity (Waste the Waist, eCOACHER, WAKEUP, Norfolk Diabetes Prevention Study, ImpulsePal, ComPoD), stopping smoking (EARS, TARS), improving self-care of heart failure (REACH-HF), reducing the decline of physical functioning in ageing (REACT) and managing depression (eMotion). He has a strong interest in research to better understand the processes of behaviour change in behavioural interventions using both qualitative and quantitative methods. His systematic reviews of "what works for supporting changes in diet and physical activity" and “diabetes prevention in the real world” have informed European evidence-based guideline (IMAGE) and NICE guidance on the prevention of diabetes, as well as the development of the English National Diabetes Prevention Programme.

He has ongoing interests in health behaviour change and in “translational physiology” – translating technical knowledge on physiology and nutrition into pragmatic interventions that can improve the wellbeing and health of people with long term illnesses.
