SPRD Scientist, Phil Stahl (ST10) is virtually judging the International Science and Engineering Fair (ISEF) on behalf of the International Society for Optics and Photonics (SPIE). Of the many 1000s of projects from around the world, 22 were selected for virtual in-person interviews. Each year more than 1,800 ninth through twelfth graders earn the right to compete at ISEF by winning a top prize at a Society-affiliated local, regional, state or national science fair. Judging will take place from May 3-6, 2021 via video conferencing.
