Jonathan Cohen, Ph.D. Professor Endowed Title C. Vincent Prothro Distinguished Chair in Human Nutrition Research School Medical School Department Center for Human Nutrition | Eugene McDermott Center for Human Growth and Development | Internal Medicine Graduate Programs Genetics, Development and Disease Biography Dr. Cohen received his Ph.D. from the University of Cape Town in 1989 then did postdoctoral studies at UT Southwestern where he has remained ever since. His research focuses on the genetic basis of metabolic disorders that contribute common diseases such as heart disease and fatty liver disease. Together with his scientific partner, Dr. Helen Hobbs, he has identified genes that play major roles in the metabolism of fats, cholesterol, and triglycerides, and elucidated the biological roles of their protein products. His laboratory showed that loss-of-function mutations in PCSK9 are associated with low plasma levels of cholesterol and confer protection from coronary heart disease. In addition, the Hobbs-Cohen laboratory identified the first genetic cause of nonalcoholic fatty liver disease in humans.
