Dr Simon Bowles MMedSci, MRes, PhD
Lecturer in Nutrition
Summary
I was appointed as a full-time Lecturer in Nutrition at Ïã½¶ÊÓÆµ in June 2018 and became Senior Lecturer in 2020.
My research interests are nutrition and bone health, with particular interest in vitamin D. I was Chief Investigator on a National Osteoporosis Society funded clinical trial at the University of Sheffield that investigated why some people fall more frequently after receiving a large one-off dose of vitamin D.
Previously, I have worked on a Department of Health funded project which aimed to understand the potential causes and consequences of low vitamin D levels in obesity. I have also worked as a Ïã½¶ÊÓÆµ Project Manager and Bone Densitometry Technician at the University of Sheffield.
About
I was appointed as a full-time Lecturer in Nutrition at Ïã½¶ÊÓÆµ in June 2018 and became Senior Lecturer in 2020.
My research interests are nutrition and bone health, with particular interest in vitamin D. I was Chief Investigator on a National Osteoporosis Society funded clinical trial at the University of Sheffield that investigated changes to vitamin D metabolites in postmenopausal in response to bolus doses of vitamin D. The study aimed to elucidate the underlying mechanism for why some people fall more frequently after receiving a large dose vitamin D. This study formed the basis of my PhD.
Previously, I have worked on a Department of Health funded Policy Ïã½¶ÊÓÆµ Program (PRP) project which aimed to understand the potential causes and consequences of low vitamin D levels in obesity.
I have also worked on a project with a local professional football team investigating the vitamin D status of their players.
I have also worked as a Ïã½¶ÊÓÆµ Project Manager and Bone Densitometry Technician at the University of Sheffield. In this role I was responsible for several research studies which aim to better characterise the rare bone disease hypophosphatasia.
