Dr. Cefalu’s research is active at both the clinical and basic levels. On a clinical level, he is interested in clinical interventions to improve the metabolic state of individuals with insulin resistance and type 2 diabetes. On a basic level, he is interested in cellular mechanisms for insulin resistance. In addition, Dr. Cefalu also serves as Director for an NIH-funded Center for the Study of Botanicals and Metabolic Syndrome at Pennington Biomedical Research Center.
