Ryan Klein graduated from the University of Chicago in 2014. He received his doctorate in inorganic chemistry from Northwestern University in 2019, where he worked in the lab of Professor Danna Freedman. His thesis centered around high-pressure inorganic synthesis and studying exotic magnetic phases at extreme conditions. In late 2019, he began his postdoctoral research position at NREL, where he works with Professor Tom Gennett in the Hydrogen Materials—Advanced Research Consortium (HyMARC). As an NREL postdoc, Ryan works remotely full time at the NIST Center for Neutron Research (NCNR) in Gaithersburg, Maryland, with Craig Brown. At the NCNR, Ryan characterizes candidate hydrogen storage materials using neutron diffraction and scattering techniques.
