Harrison joined Modern Hydrogen in 2021 as an Associate Engineer having worked previously at NASA and the Department of Energy.

He made significant contributions to the thermionics program, performing high-temperature vacuum experiments on materials and assemblies for use in the extreme environments within a thermionic converter. His contributions led to a 50x improvement in material lifetime of a critical component and opened the door to prototype- and product-spec lifetimes. He has also made significant contributions in the Hydrogen program, leading several design efforts and contributing to the completion of lab- and pilot-scale Hydrogen reactors.

Harrison received a Bachelor of Arts in Physics from Case Western Reserve University in 2017 and a Master of Science in Materials Science from Oregon State University in 2020. In his free time, Harrison enjoys cooking, hiking, biking, and playing video games.
