Biography

Geoffrey Oxnard is a thoracic oncologist at Dana-Farber Cancer Institute and an Associate Professor of Medicine at Harvard Medical School. The aims of Dr. Oxnard’s research are to develop clinical applications for cancer genotyping technologies to advance precision cancer care.

Dr. Oxnard has published extensively on sensitivity and resistance to EGFR kinase inhibitors in lung cancer with a focus on the clinical biology of the EGFR T790M mutation. More recently his research has focused on genomic analysis of plasma cell-free DNA as a diagnostic to assist in treatment planning, response monitoring, and cancer detection.

Dr. Oxnard received his BA in chemistry from Harvard University and his MD from the University of Chicago-Pritzker School of Medicine. He served his residency in internal medicine at Massachusetts General Hospital and completed his fellowship in medical oncology at Memorial Sloan-Kettering Cancer Center, joining the Dana-Farber faculty in 2011.
