At NREL Since: 

Dan Ruddy received a Ph.D. degree in Inorganic Chemistry from the University of California, Berkeley in 2008. His research combined synthetic molecular and materials chemistry with detailed characterization to study novel heterogeneous catalysts. He then worked on a variety of catalyst development projects at the Dow Chemical Company in the Renewable Feedstocks & Process Catalysis Group before joining the Chemical and Nanoscale Science Group at NREL in 2010. Dr. Ruddy's research at NREL integrates the synthesis and characterization of functional molecules and materials for advanced energy technologies including solar fuels production, biomass conversion catalysis, and next-generation PV materials.
