This biennial event showcases the impact, value, and range of federally funded research and programming that takes place across Johns Hopkins University and Medicine. Lawmakers, congressional staff, media and the general public can engage directly with scientists and their discoveries, including memorable, hands-on experiences. The last in-person event in 2019, which featured 21 teams representing all parts of the university, received funding from 16 different government agencies, including the Department of Energy, the National Science Foundation, the Department of Defense, NASA, and the National Institutes of Health. The 2021 event was held virtually.
