(2017-2019) - MENTOR: Karl Bilimoria, MD
Dr. Ellis’ research centers on surgical quality improvement and outcomes research pertaining to complex surgical oncology under the guidance of his mentor, Dr. Karl Bilimoria. Specifically, he is focusing on hepatopancreaticobiliary (HPB) surgery and factors associated with adverse outcomes in this patient population. Dr. Ellis is also studying the effects of regionalization of complex surgical care, as well as developing national quality standards for management of patients before and after HPB surgery. This includes research examining what factors drive patients to choose one hospital or surgeon over another prior to having surgery. Dr. Ellis is an American College of Surgeons Clinical Scholar as well as a T32 postdoctoral fellow at the Northwestern Center for Healthcare Studies. He obtained a master’s degree in Health Services and Outcomes Research at Northwestern University during his research time.
