Ike Okosun CV
Dr. Ike Okosun is a Professor of Epidemiology and Biostatistics in the Department of Population Health Sciences. His research focuses on investigating the epidemiology of metabolic syndrome, including obesity, diabetes, hypertension and dyslipidemia in populations of African origin.
"We are entering a new epoch of understanding on how the genome interacts with the environment to produce diseases," Dr. Okosun says. "There is now emerging evidence that epigenetic factors play important role in regulating and maintaining factors of metabolic syndrome, and strong evidence for a complex interaction of genetic and environmental factors that influence the risk of metabolic syndrome in each individual."
His current research involves investigating epigenetic markers underlying increased risk of high blood pressure and type 2 diabetes in populations of West-African ancestry. His aim is to disentangle the scientific puzzle of these diseases by exploring the role and relative contribution of (1) environmental changes due to migration and (2) the effect of migration on epigenetic modification via patterns of DNA methylation. The premise of his research is that environmental changes following migration alters DNA methylation levels creating epigenetic signature and subsequent increase in high blood pressure and type 2 diabetes.
Dr. Okosun is a member of many scientific organizations and editorial boards. He is a Fellow of the Royal Society of Public Health, The Obesity Society, and a member of the Board of the The American College of Epidemiology (ACE).
