Biography
Dr. Jeff Horowitz is a professor of Movement Science and director of the Substrate Metabolism Laboratory (SML) at the University of Michigan School of Kinesiology. Before his time at U-M, Dr. Horowitz was a research instructor for the Division of Gastroenterology at the Washington University School of Medicine in St. Louis, MO. Dr. Horowitz completed his PhD in Exercise Physiology at University of Texas at Austin.
Dr. Horowitz has published more than 70 articles in peer-reviewed journals, and he has received more than $10 million in grant funding from the National Institute of Health and foundations/organizations such as the American Diabetes Association. Dr. Horowitz is an Associate Editor for the journal "Diabetes", and he is a standing member of the NIH grant review study section entitled, "Human Studies in Obesity and Diabetes (HSDO).

Research
Dr. Horowitz's primary research focus is on the effects of exercise and diet on the regulation of lipid metabolism, insulin resistance and other obesity-related cardio-metabolic abnormalities in human subjects. His laboratory studies whole-body and regional fatty acid and glucose metabolism in human subjects using stable-isotope tracers, microdialysis, and indirect calorimetry. In addition, his lab also examines cellular regulation of substrate metabolism, insulin signaling, adipogenesis, and inflammatory pathway activation in skeletal muscle and adipose tissue. This integrated approach makes it possible to identify cellular adaptations to exercise and/or different diets that may underlie important clinical outcomes. Dr. Horowitz is also the Director of the “Nutrition, Exercise, and phenotype Testing (NExT)” core for the University of Michigan’s NIH-funded “Nutrition and Obesity Research Center” (MNORC). In his role as Core Director, he assists university researchers with their obesity-related research projects by helping to conduct and/or coordinate a wide range of metabolic and phenotypic assessments.
