As a fully trained tumor immunotherapist and surgical oncologist, he has expertise in the treatment of primary, regionally advanced and metastatic melanoma, soft tissue sarcoma and breast cancer. His research interests and laboratory investigate mechanisms of immune evasion by solid tumors to targeted and immune checkpoint blockade and prognostic markers of response to immune based therapies including adoptive cell therapy (including melanoma, sarcoma, cholangiocarcinoma and breast cancer).

Dr. Prieto serves on the Society of Surgical Oncology's Sarcoma Disease Site Workgroup Committee and is the Cancer Center Physician Liason to the American College of Surgeons Committee on Cancer.
