1992- present: Sr. Research Associate, The Institute for Environmental Modeling, U. Tennessee
I have worked in The Institute for Environmental Modeling at the University of Tennessee. Particular areas of interest include spatial statistical applications to environmental contamination problems, exposure assessment development, fate and transport of contaminants, ecological population models, and applications of uncertainty analysis to these areas in a decision-making context. I am a co-developer and co-principal investigator for the Spatial Analysis and Decision Assistance (SADA) freeware. I develop and maintain a dynamic link library consisting of algorithms for statistical, ecological, and human health risk assessment capabilities that work in a spatial GIS context. This library is used in SADA and has also been used in the FIELDS ArcGIS add-in software produced by EPA Region 5. In addition to coding, I am active in all areas of software project development for SADA; including software design, creating and maintaining the web page, documentation and help file development, procurement of funding, software verification and validation, distribution testing, and conducting multi-day software training sessions.
