In 1994, the National Institutes of Health awarded Dr. Hyer the "NIH Outstanding Research Award for Clinical Trainees." Trained in public health at Walter Reed Hospital and Harvard University, Commander Hyer supported four major military operations in the European, African, and southwest Asian theatres to include service as Chief Public Health Advisor for the Kosovo operations and Deputy Surgeon for the Mozambique flood relief operations. Dr. Hyer then spent 4 y at the World Health Organization (WHO) in Geneva as the first WHO Civil Military Liaison Officer and served as part of the WHO's outbreak response team to deadly outbreaks like anthrax, SARS, and avian influenza as well as having organized missions during the 2005 Tsunami response. His experiences with the media in outbreaks and emergencies led him to coauthor the popular WHO handbook, Effective Media Communication During Public Health Emergencies.

Appointed a U.S. Congressional Fellow for Senator Pete V. Domenici (R-New Mexico), he helped introduce legislation to safeguard genetic privacy that eventually became the Genetic Information Non-discrimination Act (GINA) of 2008.
