Regeneron ISEF

The Next Generation of STEM Leaders

Every year, tens of millions of students participate in science fairs around the globe but only about 1,800 earn the right to compete for nearly $5 million awards bestowed each May at the Regeneron International Science and Engineering Fair (ISEF). In 2021, the competition will take place virtually in order to keep our finalists, volunteers, judges and staff safe during the ongoing coronavirus pandemic.
