Christopher is Chief, Occupational Medicine and Senior Flight Surgeon for the United States US Air Force at Joint Base Elmendorf Richardson in Alaska. He recently completed the Occupational and Environmental Medicine Residency (OEMR) program for physicians at the Harvard T.H. Chan School of Public Health. At Harvard, his research focused on a comprehensive review of current research on the health impacts of commercial flight—such as circadian rhythm disruption, decreased cardiopulmonary function, and flight anxiety—on both aircrew and passengers. In a separate project, he helped evaluate the hazards of cosmic ionizing radiation and its effects on the health of aircrew and passengers, specifically looking at cancer risk and reproductive health outcomes.
