Research Interests

Scientific Project Management

Amie Sluiter manages projects from exploratory science with industrial partners to multimillion dollar, cross-laboratory U.S. Department of Energy research projects. Excellent technical writing skills, as well as written and verbal communication skills, make these endeavors enjoyable and successful for her. She is well versed in all aspects of project management, from planning and change control, to managing personnel and technical oversight. She is highly organized, with a technical background that lends itself to project participation and technical monitoring.

Biofuels Sample Characterization

Amie began research in the biofuels field in 1996. She has extensive experience in wet chemical analysis, method development, and data quality review. She joined the Biomass Analysis Technologies team at the National Renewable Energy Laboratory (NREL) to provide compositional analysis data on biomass feedstocks and process intermediates for use in pretreatment models and techno-economic analyses. Amie has investigated a number of biomass analysis methods and is primary author on 11 Laboratory Analytical Procedures, which are extensively used worldwide. She has taught full biomass compositional analysis procedures to both internal and external colleagues, including international partners. Amie has created calculation spreadsheets to facilitate the hundreds of calculations involved in summative mass closure analysis.

Near Infrared Predictive Modeling

Amie is responsible for the creation and maintenance of many of NREL's rapid near-infrared (NIR) spectroscopic analysis methods. These methods allow analysts to predict the composition of feedstock and process intermediates at a significant time and cost reduction compared with traditional wet chemical analyses. Amie evaluates wet chemical analyses on a number of biomass feedstock and intermediate types, and she creates projection to latent structures and principal component analysis (PCA) NIR models to predict constituent values. She has published a number of these models, and they range from mature to exploratory.
