Brief Profile

Dr.S.Ahamed Ibrahim obtained his M.Sc degree in medical biochemistry from JIPMER, Pondicherry and PhD in biochemistry from Christian Medical College and Hospital, Vellore.  He joined the institute in 1997 and presently heading the lipid chemistry division. Dr.Ibrahim’s research work is focused on optimal fat requirement for the prevention of diet related chronic diseases such as diabetes, inflammatory bowel disease, nonalcoholic fatty liver disease. His earlier studies showed that dietary saturated and trans fatty acids induce insulin resistance and compared to saturated fatty acids, trans fatty acids induce insulin resistance to a greater extent. Studies also showed that maternal intake of trans fatty acids predispose the offspring to insulin resistance and possibly increasing the risk of developing type 2 diabetes in later life.  Currently studies are in progress to understand the role of dietary fatty acids in the development and progression of nonalcoholic fatty liver disease.  Our future research plan also involves investigation of the role of gut-liver axis in the development and progression of nonalcoholic fatty liver disease.  He is a research supervisor in biochemistry at Osmania university, Hyderabad and presently guiding two PhD students.
