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 and diagnostic development and host-pathogen studies on V. cholerae (the cause of cholera), Salmonella enterica serovar Typhi (the cause of typhoid fever), and Shigella spp. (a cause of bacillary dysentery). 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 (GTEN), a CDC-sponsored national consortium focusing on global infectious diseases and evaluating vaccination strategies and use among global international travelers, as well as the acquisition of highly drug resistant bacteria during travel. 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, Harvard School of Public Health, and Harvard College, teaches students, residents and fellows at the MGH, and teaches in a number of post-graduate courses at Harvard Medical School and internationally.

Research at the MGH is interwoven throughout more than 30 departments, centers and units and is conducted with the support and guidance of the MGH Research Institute. The Research Roundup is a monthly series highlighting studies, news and events.
Study finds multiple strains of cholera exist simultaneously in Dhaka and frequently, one individual may have several at a given time which may lead to genetic transfers and the formation of new strains
quotes MGH physician Edward Ryan
In a recent article two Massachusetts General Hospital physicians describe the best ways to prevent mosquito bites and the illnesses –including Zika virus – that might be contracted from them.
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.
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.
