Summary

Dr. Hari Nathan is an Associate Professor of Surgery and Chief of the Division of Hepato-Pancreato-Biliary Surgery at the University of Michigan. Dr. Nathan completed both his undergraduate and medical education with honors at The Johns Hopkins University. He was awarded a PhD in Clinical Investigation from The Johns Hopkins Bloomberg School of Public Health. He completed his general surgery residency at The Johns Hopkins Hospital and a clinical fellowship in complex general surgical oncology at Memorial Sloan Kettering Cancer Center, where he also served as the Chief Administrative Fellow in Surgery. He joined the faculty of the University of Michigan in 2014.
Dr. Nathan’s clinical focus is on tumors of the liver, bile duct, pancreas, and stomach. He has particular interests in the treatment of liver metastases from colorectal cancer and directs Michigan Medicine’s Hepatic Artery Infusion Pump (HAIP) Program. He also serves as the Surgical Director of the Multidisciplinary Pancreatic Cancer Clinic.
Dr. Nathan’s research seeks to identify strategies to improve outcomes and control costs for surgical care. His work has been funded by the Agency for Healthcare Research and Quality and the National Institute on Aging. He has done substantial work on the quality of cancer surgery and prediction of prognosis after cancer resection. More recently, his research has focused on variation in surgical quality and costs within hospital networks. He was awarded the 2018 American College of Surgeons Joan L. and Julius H. Jacobson II Promising Investigator Award.
Dr. Nathan is heavily involved in regional efforts to improve healthcare value. He is the Director of the Michigan Value Collaborative, a coalition of 87 Michigan hospitals focused on improving healthcare value in Michigan. He is also the Co-Chair of the Cancer Steering Committee for the Michigan Surgical Quality Collaborative (MSQC) and directs MSQC efforts to standardize pancreatectomy care across Michigan.
