The Office of the Health Commissioner sets policy and provides leadership for the Department of Public Health. We work closely with other human service providers in Philadelphia to assure high-quality healthcare services for all.
James W. Buehler, MD, is Health Commissioner for the City of Philadelphia. Before joining the Department of Public Health, he was a Professor in the Department of Health Management and Policy at the Drexel University School of Public Health, where his interests in public health systems and services research centered on the uses of population health information in public health practice, connections between healthcare and public health services, and the population health applications of health information automation.
Previously, Dr. Buehler served as the Director of the Public Health Surveillance & Informatics Program Office at the U.S. Centers for Disease Control & Prevention (CDC) in Atlanta. This Office managed several nationwide population health monitoring systems, including the National Notifiable Diseases Surveillance System, the Behavioral Risk Factor Surveillance System, and the BioSense 2.0 syndromic surveillance system. The Office was also the focal point at CDC for addressing cross-cutting issues in public health surveillance and informatics, most notably the public health opportunities arising from the growing use of electronic health records.
From 1981 through 2002, Dr. Buehler was a Commissioned Officer in the U.S. Public Health Service at CDC, where he worked in a variety of areas, including general field epidemiology, maternal and child health, HIV/AIDS, STD, and TB prevention, and, briefly in in the Fall of 2001, anthrax. In 2002, he joined the faculty of the Rollins School of Public Health at Emory University as a Research Professor in the Epidemiology Department, where he also served as a consultant to Georgia’s state health department. In 2009, he returned to CDC to contribute to the national response to H1N1 pandemic influenza.
