James Gangwisch, Ph.D. is an Assistant Professor at the Columbia University Medical Center. His research has focused on the relationship between sleep duration, nutrition, psychiatric disorders, and cardiometabolic diseases. The study that he led linking inadequate sleep to obesity helped motivate the National Institutes of Health, National Heart, Lung and Blood Institute to release a request for proposals on "The Mechanisms Linking Short Sleep Duration and Risk of Obesity or Overweight". He led the first studies to show associations between short sleep duration and the incidences of hypertension and hypercholesterolemia and has led studies exploring sleep duration as a risk factor for diabetes, mortality, and depression.
