Applying catalysis and reaction-engineering approaches, the role targets low-carbon fuel pathways-such as hydrogen, ammonia, synthetic and electro-fuels, sustainable aviation fuel, and fuels derived from biomass, waste plastics, or carbon dioxide (CO)-spanning catalyst and process development, reactor design and scale-up, and performance and techno-economic assessment. Develop catalytic and/or electrocatalytic routes and materials for alternative-fuel production (e.g., hydrogen, ammonia, electro-fuels, and CO- or biomass-derived fuels), including synthesis, testing, and kinetic measurement.
