Narrative:
My area of expertise at EPA is the improvement and analysis of air emission data components of urban and regional air quality modeling. The focus is on the modeling of emissions to the air, including methods to fill gaps in reported data and to better temporally, spatially, and chemically allocate annual emission data to the hourly gridded form needed for air quality models, particularly the Community Multiscale Air Quality (CMAQ) model. This has included service as project officer for the Sparse Matrix Operator Kernel Emission (SMOKE) model, which is an operational modeling system maintained and improved by the EPA Office of Air Quality Planning and Standards

More recent work includes ongoing research on the current and future (ca. 2050) spatial and temporal behavior of emissions as part of the EPA Climate Impact on Regional Air Quality (CIRAQ) program, and oversight of the development of other emission tools, such as the open software Spatial Allocator for gridding and reprojecting air quality data. I also participate on the OAQPS-led team for the Emission Modeling Framework (EMF), and on the joint Emission Modeling Team. I serve as Task Order Project Officer for AMAD’s primary modeling support contract, and as contract Project Officer on the Community Modeling and Analysis System (CMAS) Center. CMAS was established under a cooperative grant to the University of North Carolina (UNC) for the purpose of encouraging the modeling community to share in the support and further improvement of the CMAQ family of air quality modeling tools.
