Dr. Peabody is a Professor at the University of California and the Deputy Director of the Institute for Global Health. Dr. Peabody has been a member of the departments of medicine, epidemiology and biostatistics, and health services at the University of California since 1995. He is also the senior vice president and chief medical officer for Sg2 a health care intelligence company based in Chicago that works with health leaders and scientists in the US and around the world. As an experienced clinician, academician and executive, Dr. Peabody provides expert direction for the organization, financing and development of health care systems, as well as the quest for quality and improved outcomes.

Before returning to the University in 2007, John served as the senior director of health economics at Amgen, leading the development of the policy, service delivery, access and reimbursement strategies associated with the global adoption of new oncology therapeutic technologies. Since 1995, Dr. Peabody has been a faculty member in the departments of medicine, epidemiology and biostatistics, and holds a joint appointment in health services at the University of California, Los Angeles. In 1999, he was elected a fellow of the American College of Physicians. Before joining the university, John worked for the RAND Corp, the World Health Organization, the World Bank and Project Hope in China.

Dr. Peabody is an international leader in measurement, health policy, health systems, and quality of clinical care. He has authored more than 200 peer-reviewed publications and several books on healthcare, health economics, the quality of clinical practice, impact assessment, and health care systems throughout his career. John is a featured speaker at numerous meetings and educational events. Dr. Peabody is currently a National Institutes of Health (NIH) funded investigator, sits on the prestigious Institute of Medicine committee for cardiovascular disease, and has active academic appointments at two University of California campuses. His leadership in this arena has led to his placement on blue ribbon panels, to give congressional testimony and sit on peer review expert committees, lead and World Health Organization task forces. Dr. Peabody leads both large scale NIH sponsored investigations on changing how value is determined and consulted with sophisticated entrepreneurial firms intent on making a difference in health care.

Dr. Peabody's work focuses on the leading economic challenges of our day: identifying tests, therapeutics and practices that will lead to better health for patients at a lower cost to payers. The fundamentals of this approach are to begin by quantifying potential benefits and then extend this to examine real world clinical practice. At its core this more sophisticated approach means understanding clinical decision making. To do this Dr. Peabody developed a globally adopted standard for measuring clinical practice variation, known now simply as CPVTM. CPVTM and this approach has been used by companies, physician groups, hospitals, payers and governments around the world to establish the value of products and practices.

Dr. Peabody is a board-certified internist. A Stanford University graduate, he received his MD from UCSF, his diploma in tropical medicine and hygiene (DTM&H) from the University of London, and his master of philosophy and a MS and a PhD in public policy from the RAND Graduate School.
