My career goal is to improve cancer outcomes by defining the best roles for imaging-based technologies in cancer care. I am an abdominal radiologist and health outcomes researcher at Massachusetts General Hospital, and Director of the MGH Institute for Technology Assessment. My research is centered in imaging, decision science, and risk analysis, with a focus in cancer modeling. I have studied the role of imaging technologies in multiple cancer settings, but have focused in renal and pancreatic cancers, and in radiation-induced cancer risks. Leveraging decision science methods, we have established - or refuted - the effectiveness and cost-effectiveness of imaging technologies in several clinical scenarios, and have brought new evidence and insights to their role in cancer care.
