My research focuses on catalysis and reaction engineering. My group combines experimental measurement with theoretical analyses of reaction mechanisms in order to better understand and improve catalytic processes. The operating conditions of the reacting systems we have studied include gas phase reactions at temperatures up to 800°C, liquid phase reactions at room temperature and below, and reactions in presence of a strong electric field. The experimental techniques include steady and unsteady (transient) state kinetics measurements, adsorbed species identification using diffuse reflectance Fourier transform infrared spectroscopy and measurement of isotopic species using mass spectrometry.

My current research involves thermochemical conversion of biomass to fuels and chemicals.  We are investigating both conversion of natural fats and oils to diesel fuel and petrochemicals, and conversion of lignocellulosic biomass to hydrocarbon fuels and chemicals.  Although the “refining” of biomass has analogies to refining of petroleum, biomass is highly oxygenated, and conversion to hydrocarbons requires new catalysts, reactors and reaction conditions that differ greatly from those used in petroleum refining.  A huge challenge in development of these biomass conversion systems is the smaller scale at which they must operate due to the distributed nature of biomass resources.
