Dr. Ryan has been elected to Fellowship of the American College of Physicians and the Infectious Diseases Society of America, and has published over 150 peer-reviewed journal articles and book chapters on enteric infections, infectious diseases, vaccines, and tropical medicine. Dr. Ryan is a Senior Editor of Hunter's Tropical Medicine, 9th Edition.
Dr. Ryan's research focuses on clinical studies of illnesses associated with residing in, immigrating from, or traveling through resource-limited settings. His research is funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID) and the U.S. Centers for Disease Control & Prevention (CDC). Dr. Ryan is the principal investigator on research projects focusing on enteric vaccine development, host-pathogen studies on V. cholerae (the cause of cholera) and Salmonella enterica serovar Typhi (the cause of typhoid fever). Particular areas of focus include the application of high throughput genomic, proteomic, immunoproteomic, and web-based platform technologies to these illnesses. Dr. Ryan is also the Director of Global TravEpiNet, a CDC-sponsored national consortium focusing on global infectious diseases and evaluating vaccination strategies and use among global international travelers. He is the principal investigator and program director for a Fogarty International Center, National Institutes of Health (NIH)-sponsored Training Program in Vaccine Development and Public Health between Harvard-MGH and the ICDDR,B in Dhaka, Bangladesh. Dr. Ryan teaches tropical medicine and infectious diseases in the core curricula at Harvard Medical School and the Harvard School of Public Health, teaches students, residents and fellows at the MGH, and teaches in a number of post-graduate courses at Harvard Medical School and internationally.
International travel is the primary way many infections traverse the world. Despite these potential risks, a recent study conducted by the Division of Infectious Diseases found that 46 percent of travelers to resource-limited countries did not seek health advice or vaccinations prior to departure.
Not only do U.S. travelers to West Africa who consult health providers before they leave and take prescribed preventive medications substantially reduce their risk of contracting malaria, they also reduce costs to their health insurance providers and, in most cases, to themselves.
