Dr. Ronnekleiv-Kelly is an assistant professor in the Department of Surgery, Division of Surgical Oncology at the University of Wisconsin School of Medicine and Public Health, Madison WI. He specializes in treating patients with gastrointestinal malignancies and sarcoma with a clinical focus on hepatic, biliary and pancreatic malignancy.

Dr. Ronnekleiv-Kelly’s research focuses on pancreatic and liver cancer (fibrolamellar carcinoma). Specifically, his laboratory uses complex pre-clinical mouse models of cancer in conjunction with in vitro studies to understand how an environmental sensor class of proteins (including aryl hydrocarbon receptor and circadian proteins) affects pancreas and liver cancer development and spread. Additionally, his laboratory seeks to understand how these proteins impact the various cell populations in the cancer tumor microenvironment, and how to target them for therapeutic effect.
