Gregory C. Gray MD, MPH, FIDSA is a Professor at Duke University with 3 affiliations: the Division of Infectious Diseases in Duke University's School of Medicine, Duke Global Health Institute, and Duke Nicholas School of the Environment. He also serves part-time as a Professor in the Program in Emerging Infectious Diseases at Duke-NUS Medical School, Singapore and as a Professor of Global Health at Duke Kunshan University in China. He has visiting professorship positions in six other academic institutions in China, Romania, Australia, and the USA. His medical boards are in Preventive Medicine and Public Health. Dr. Gray has conducted diverse epidemiological studies of infectious diseases for 25 years in 5 continents. Much of his work has involved identifying risk factors for occupational diseases, particularly for infectious diseases. He has studied numerous occupational groups including farmers, animal breeders, veterinarians, military personnel, turkey workers, poultry workers, horse workers, hunters, and pig workers. A strong supporter for the One Health approach, he has won multiple One Health research and training grants, established two centers of One Health (USA & Romania) and developed 4 graduate programs in One Health (PhD, MHS, Certificate and Program). He has mentored more than 50 graduate students, postdocs, and international scholars in research and often guides their work to peer-reviewed publication. He has served on numerous national expert advisory committees including those associated with the US Armed Forces Epidemiological Board, the Infectious Disease Society of America, and the Institute of Medicine. He has authored more than 260 scientific reports and book chapters in the peer-reviewed medical literature. Currently, he serves on the Editorial Board for the journals Influenza and Other Respiratory Viruses and Tropical Diseases,Travel Medicine and Vaccines.
