Ryan J. Ellis conducts research in surgical oncology, focusing on cancers and diseases of the pancreas, liver, and bile ducts. Much of the work examines how surgical care is delivered and organized, including hospital procedure volumes, patient travel to specialized centers, and strategies to prevent infections and complications after major cancer operations. Some studies also address the use of prophylactic antibiotics and treatment patterns drawn from large national cancer databases.
