A Scientist working in lab

There are very few centers in the world that are 100 percent devoted to diabetes research and care — and Joslin is one of them. As a result, our researchers are bringing us closer to a cure. Each year, we make great headway in understanding the underlying cause of diabetes, as well as how to help prevent its complications.

The research arm of our institution is large. About 250 researchers in 30 different labs are uncovering new information about type 1 and type 2 diabetes. In 2018, our researchers were awarded $24 million in grants from the National Institutes of Health (NIH). Today our team uses these funds to lead 288 IRB-approved studies that will set the standards for diabetes care around the world.

Our team’s deep commitment to research results in the publication of hundreds of scientific papers in peer-reviewed journals each year. Researchers and clinicians all over the globe rely on Joslin to be at the forefront of diabetes care — and we’re proud to serve the medical and scientific community in this way.
