Research Interests

Our group investigates reactions at solid surfaces for renewable and sustainable energy applications. We are particularly focused on interfacial chemistry important in the conversion of biomass to fuels and chemicals. Biomass-derived carbohydrates and lipids contain a high degree of oxygenate functionality, and it is a major challenge to develop new catalysts capable of selective conversions of the oxygenates to useful fuel and chemical products. A major focus of our group is to design such catalysts based on a molecular-scale understanding of the oxygenate-catalyst interaction. We also conduct research in interfacial chemistry related to hydrogen fuel cells—in particular, we are interested in gaining a fundamental understanding of how key physical features of the electrocatalytic interface control the mechanisms for key reactions, so that improved electrocatalysts can be designed.

Our efforts to research various applications are united by a common theme: quantum chemical calculations are used in direct combination with experimental techniques to obtain a detailed understanding of chemical and physical phenomena at solid surfaces. Having this understanding in hand allows us to design improved catalysts that we can screen under realistic conditions in chemical reactors. With the rapidly expanding speed of modern computers, these kinds of combined experimental/theoretical studies are poised to have a major impact on all branches of science and engineering research.

Our research focuses on the following main areas:

  • Surface reactivity and catalyst design of multifunctional oxygenates
  • Model studies of electrocatalytic interfaces
  • Developing enhanced biomass tar reforming catalysts
  • Catalysis for diesel production from biomass-derived lipids
  • Fundamental investigations metal – metal oxide – organic interfaces
