Toni K. Choueiri is a Lebanese American medical oncologist and researcher. He is the Jerome and Nancy Kohlberg Professor of Medicine at Harvard Medical School and Director of the Lank Center for Genitourinary Oncology at the Dana–Farber Cancer Institute. His work has led to the establishment of several novel drugs (cabozantinib, avelumab, pazopanib and others including combinations) and prognostic factors in advanced renal cell carcinoma (RCC). Choueiri also co-established the International metastatic database Consortium with Daniel Heng. His biomarker work has shed light on complex immunogenomics mechanisms contributing to response and resistance to targeted therapy and immunotherapy.[1][2]
