Design, synthesize, and test heterogeneous catalysts (e.g., supported metals, oxides, single-atom systems, and high-entropy metal alloy systems) and operate catalytic reactors to measure activity, selectivity, and kinetics for targeted thermo- and/or electrocatalytic reactions. The role integrates catalyst synthesis, high-throughput reactor testing, and in situ/operando characterization with machine-learning and agentic artificial intelligence (AI) methods that propose, prioritize, and interpret experiments, accelerating the discovery and optimization of catalytic materials for energy and sustainability applications.
