Stephen is a programmer with the ICESat-2 Science Computing Facility, and the ATLAS Flight Science Receiver Algorithms team.  He started at NASA looking out into space as an astrophysicist, with the Swift Gamma-Ray Burst Explorer mission, but since 2014 has been focusing on Earth with the ICESat-2 mission. Working with the mission team has been a highlight, he said, and he’s looking forward to putting the tools he’s developing to work when ICESat-2 launches.
