The NIH Research Festival is an annual multi-day showcase on the NIH campus in Bethesda that highlights intramural biomedical research through lectures, symposia, poster sessions, exhibits, and interactive demonstrations. Organized by the National Institutes of Health, the festival brings together scientists, trainees, staff, and visitors to share recent research advances, career-development resources, and opportunities for cross-disciplinary collaboration. It is notable for spotlighting the breadth of NIH’s scientific programs and fostering internal and public engagement with biomedical research.
