Research Summary:

While a key member of the Division of Nephrology, Dr. Saran is based at the Kidney Epidemiology and Cost Center (KECC) in downtown Ann Arbor, because of his interest in outcomes research. His main research interests revolve around Cardiovascular Disease in Chronic Kidney Disease, and the epidemiology of Vascular Access in Hemodialysis. He is PI on a 4-center CKD study and is co-investigator on a number of observational studies (DOPPS, CRIC, PPS) and involved with multi-center clinical trials (FHD). Trainees from Nephrology and Internal Medicine regularly participate in bimonthly research meetings with a designated Cardio-Renal Group and weekly to bimonthly research meetings at the KECC as well as at the Arbor Research Collaborative for Health (formerly the University Renal Research and Educational Association (URREA)), an internationally recognized not-for-profit research organization closely affiliated with KECC where there is ample opportunity to be involved with projects under his supervision.
