Matthias Kretzler, M.D. Professor, Internal Medicine Research Professor, Computational Medicine and Biology University of Michigan Email: kretzler@umich.edu Dr. Matthias Kretzler graduated from the University of Heidelberg, Germany. He completed his internal medicine residency and a nephrology fellowship at the University of Munich, Germany. He is a past research fellow in physiology and nephrology at the University of Michigan, and has a special interest in the diagnosis and management of glomerular diseases and diabetic kidney disease. Dr. Kretzler is a Warner-Lambert/Parke-Davis Professor of Internal Medicine/Nephrology and Computational Medicine and Bioinformatics. The overarching goal of Dr. Kretzler’s research team is to define renal failure in mechanistic terms and use this knowledge for targeted therapeutic interventions. To reach this goal, he has developed a translational research pipeline centered on integrated systems and biology analysis of renal disease. He leads the Nephrotic Syndrome Research Network (Neptune) in the Rare Disease Clinical Research Network II, the coordinating center of the CureGN research network. He serves as the Director of the Applied Systems Biology Core at the Michigan Kidney Center and also works in the NIH Acceleration of Medicine (AMP) program in autoimmunity. He has 20 years of experience in integration of bioinformatics, molecular and clinical approaches, and has published more than 230 papers. He and his team perform data integration of large-scale data sets in international multi-disciplinary research networks in the U.S., Europe and China. These studies involve carefully monitored environmental exposures, genetic predispositions, epigenetic markers, transcriptional networks, proteomic profiles, metabolic fingerprints, digital histological biopsy archive and prospective clinical disease characterization. The molecular mechanism identified in these studies has resulted in new disease predictors and the first successful Phase II trial of a novel therapy in diabetic kidney disease in two decades.
