For enquiries, please contact - SMPH-West-Operational@sheffield.ac.uk
I trained in Physiology at The University of Sheffield and continued at Sheffield for my PhD in Nutrition in the mid-1990s under the supervision of Professor Hilary Powers and Dr David Rumsey. I then worked as a post-doctoral researcher in the MRC Dunn Nutrition Unit in Cambridge and worked at the MRC field station in The Gambia, West Africa. On my return to the UK I was appointed as a Lecturer in Human Nutrition at Newcastle University. In 2003 I re-joined the University of Sheffield as a lecturer in Human Nutrition. I was promoted to Senior Lecturer in 2010.
- Research interests
-
My research interests are the role of diet in the prevention of chronic disease, healthy ageing and diet and male fertility. I am interested in dietary strategies to improve musculoskeletal health, diet and digestive health and in the use of technology to assess dietary intake and to support healthy behaviours. I am a member of the University of Sheffield Healthy Lifespan Institute and co-lead the lifestyle intervention work-stream. I am also a member of the Institute for Sustainable Food. I have over 20 years’ experience of conducting nutrition intervention trials and a track record of successfully working with and leading multi-disciplinary research teams.
I am a member of the University of Sheffield’s Healthy Lifespan Research Institute and co-lead the ‘non-clinical lifestyle intervention’ workstream.
