PhD, MSc, BSc

Director of Biomedical Research
Director of the Institute for Biomedical and Bioscience Research
The University of Buckingham

Special Interests:
The Mediterranean Diet and Cardiovascular Health
Obesity, diabetes and the development of CVD
Links between chronic low-grade inflammation, oxidative stress and cardiovascular diseases


Mohamed was awarded his BSc Biochemistry and his MSc Nutrition and Human Physiology from the School of Sciences and his PhD from Medical School, (University of Burgundy, France) where he worked on the effect of metformin (oral anti-diabetic drug) on hepatic protein metabolism regulation.

Mohamed joined the Clore laboratory in 2005 to bring his extensive experience in metabolic diseases acquired at Dospharm Biotech Company and the European Centre of Bioprospectives (Normandy, France) where he was managing collaborative research with Lipha-Merck, Air Liquid Sante and Beaufour-IPSEN on the investigation of novel drugs for the treatment of degenerative diseases such as Alzheimer’s and diabetes.

Mohamed is Director of the Institute for Biomedical and Bioscience Research (IBBR). He is leading the University research group in Biomedical Research. The group is investigating the beneficial effects of pharmaceutical drugs and plant-based medicines on inflammation, oxidative stress, obesity, type 2 diabetes, and neurodegenerative diseases in partnership with our academic and industrial collaborators.

Mohamed has been involved in public health education and preventive programmes, delivering public lectures and seminars, on adult and childhood obesity, type 2 diabetes and cardiovascular complications, as well as on the cross-talk between metabolic and neurodegenerative diseases. He is the author, and co-author of more than forty scientific and research publications, including refereed journal articles, refereed conference and workshop papers.
