Biography

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 Associate Director at the School of Postgraduate Medicine & Allied Health. He is leading the University research group at Buckingham Institute for Translational Medicine (BITM). 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.
