About Zachary Stiles


Dr. Stiles is a surgical oncology fellow at Roswell Park Comprehensive Cancer Center. He completed general surgery residency at the University of Tennessee Health Science Center (UTHSC) in Memphis, Tennessee where he also served as Administrative Chief Resident.

During residency he completed a two-year research fellowship at the UTHSC Cancer Research Center focusing on the translational applications of mucin and micro-RNA expression in pancreatic adenocarcinoma. In addition, he simultaneously obtained a Master's of Science in Epidemiology from the UTHSC College of Graduate Health Sciences. His clinical research has focused on the application of minimally invasive approaches to complex oncologic operations and the use of large datasets to study disease and surgical outcomes.
