I am a Senior Researcher and Manager at the National Renewable Energy Laboratory's National Bioenergy Center in Golden, Colorado. I have experience in the technical management of research projects for both governmental and private clients, including financial management, training and supervision of research staff, subcontract monitoring, and general laboratory management.

I currently lead the Biomass Compositional Analysis section, a team of more than a dozen researchers and technicians providing analytical chemistry support to both internal and external clients. Our section is best known for our publicly available Laboratory Analytical Procedures (LAPS), which provide detailed methods for the summative analysis of biomass materials. Learn more about NREL Laboratory Analytical Procedures.

Research Interests

My research interests focus on developing rapid analysis techniques for the chemical characterization of biomass and using multivariate analysis techniques for the exploratory data analysis (EDA) of large multivariate data sets. I'm currently working on a number of interesting projects:

  • Developing rapid compositional analysis methods for pretreated corn stover slurries and liquors using NIR spectroscopy
  • Investigating biomass sorghum as a cellulosic ethanol feedstock, including the development of a rapid calibration equation for sorghum (with the National Sorghum Checkoff Program and Texas A&M University)
  • Developing rapid compositional analysis methods for miscanthus using NIR spectroscopy (with Idaho National Laboratory)
  • Researching the effect of reduced production inputs on the composition and bioconversion of cool-season perennial grasses (with Colorado State University)
  • Developing rapid compositional analysis methods for lipids in algae.

Previous research projects focused on measuring and understanding the behavior of very low concentrations of volatile organic compounds (VOCs) in air. I led work to develop a low-cost, real-time VOC sensor for indoor environmental monitoring using chemometric techniques to extract concentration information from multivariate sensor array data. I also performed chemometric analyses of ambient air sampling data collected at NREL to develop "chemical fingerprints" of indoor environments. For this work I led the design of a microcontroller-based automated ambient air sampler.
