Now is the perfect time to find out how medical discoveries are made by applying for an NIH internship. The National Institutes of Health offers one of the most respected research programs in the U.S. It gives students access to real projects in labs that work on cancer, neuroscience, genetics, infectious diseases, and more. Whether you’re just a high school student or you’re already completing your PhD, there’s a program suitable for your academic level and research goals.
The most popular option is the Summer Internship, open to high schoolers, undergraduates, and graduate students across the United States. Applicants get paired with NIH scientists, get involved in actual projects, and often publish or present their findings. With an acceptance rate of around 10 to 15%, getting in is competitive, but completely worth it if you’re serious about biomedical research. The NIH SIP application opens in the fall, so if this sounds like your thing, you’ll want to plan ahead.

It falls under the U.S. Department of Health and Human Services and operates as a collection of 27 different institutes and centers. They are all focused on specific areas of medical science, such as cancer, aging, mental health, and infectious diseases.
Headquartered in Bethesda, Maryland, NIH funds and conducts research aimed at improving human health and understanding disease prevention. It supports over 300,000 researchers worldwide, with a significant portion of its $45+ billion annual budget dedicated to external grants. Its current Director is Jayanta Bhattacharya, who leads its efforts in scientific discovery, global health partnerships, and national healthcare innovation.
