Jason K. Kim has 30 years focused on obesity and type 2 diabetes, and he has made a significant contribution to the field with 183 peer-reviewed publications, mostly in high-impact scientific journals. His past research has elucidated the mechanism of obesity-mediated insulin resistance and the molecular pathways by which fatty acids affect insulin signaling and glucose metabolism in skeletal muscle and liver. He has recently explored the molecular link between inflammation and insulin resistance, focusing on the macrophage and cytokine regulation of insulin action and energy metabolism using elegant metabolic procedures and molecular approaches. Our findings that macrophages and cytokines regulate insulin resistance have been cited by many important papers in the field, and my publications have received more than 34,000 citations. As a leading expert in metabolism and Director of Metabolic Disease Research Center, he  has investigated more than 400 transgenic mouse models of human diseases, collaborating with academic and industry researchers worldwide to delineate the pathogenesis of type 2 diabetes and conduct industry- standard drug trial studies for new therapies. My scientific expertise is shared globally as an Adjunct Professor at Seoul National University, Adjunct Investigator at Harvard Medical School, Dean’s Advisory Board at the University of Hong Kong, External Advisory Committee of Johns Hopkins University, Chair of NIH and American Heart Association Grant Review Committee, and scientific advisory boards of pharma. His research over the years has greatly advanced our understanding of important biological events surrounding metabolic diseases and continues to contribute toward finding new therapies to treat aging humans.
