Research Interests

  • Inorganic chemistry and catalysis

  • New synthetic pathways to functional materials

  • Renewable fuels production and processes

  • Biomass conversion catalysis

Areas of Expertise

Dan received a Ph.D. degree in Inorganic Chemistry from the University of California, Berkeley in 2008. His doctoral research combined synthetic molecular and materials chemistry with detailed characterization and performance testing of 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 Chemistry and Nanoscience Center at the National Renewable Energy Laboratory (NREL) in 2010. Ruddy's research at NREL integrates the synthesis and characterization of functional molecules and materials to enable advanced renewable fuels production and related energy technologies. Areas of expertise include:

  • Inorganic molecular and materials synthesis and characterization

  • Molecular precursor approaches to nano- and meso-scale materials

  • Compositional and morphological control

  • Surface chemistry

  • Catalysis science

    • Heterogeneous catalyst design and synthesis

    • Zeolite synthesis and modification

  • Electrocatalysis and photocatalysis

  • In-situ and operando characterization techniques


  • Ph.D., Chemistry, University of California, Berkeley, 2008

  • B.S., Chemistry, Lafayette College, 2003
