I am a staff engineer in the Biochemical Process R&D group of the National Bioenergy Center at the National Renewable Energy Laboratory in Golden, Colorado. I joined NREL in May 2008. My primary focus at NREL is on biochemical or low temperature routes, such as pretreatment and enzymatic hydrolysis, for clean sugar production from lignocellulosic biomass as intermediates to making biofuels.

I lead technical projects for industrial clients and Department of Energy programmatic research including lignocellulosic biomass pretreatment and enzymatic hydrolysis with industrial enzyme cocktails, component enzyme binding and threading, and solid-acid catalysis of biomass. I am interested in understanding and improving this process on length scales spanning from microscopic particle properties to thousands of liters in a pilot plant. I have mentored dozens of undergraduate and graduate students and was recognized with the DOE Office of Science Outstanding Mentor Award in 2010 through the Science Undergraduate Laboratory Internship (SULI) program.

Research Interests

  • Particle morphology, concentration, catalyst impregnation, and flow properties of lignocellulosic biomass as it is converted to sugars
  • Enzyme adsorption and activity
  • Fundamental measures to predict biomass recalcitrance
  • Process scale up and project management
