Spatial Analysis and Decision Assistance

People (under construction)

SADA exists because of the highly energized efforts of numerous experts across numerous disciplines in academia, the federal government, and the private sector. Some of the larger goals of all these individuals is to make SADA a capable and substantial software package in

1) Supporting scientists, engineers, environmentalists, geographers, and many others as the tackle real world applications in their field
2) Encouraging the use of "spatial thinking" in problem solving
3) Serving as a teaching aid at both the highschool and university level
4) Serving as a foundation to test new or advanced approaches in a friendly to use environemnt.

Most certainly we have inadvertently left some important people off the list. If this has happened please let us know.

Robert Stewart
Project Manager, Lead Developer, & Education

Robert first created the SADA software package in 1995 and has been the project manager and lead developer ever since. His interests lie in the integration of geospatial analysis methods with risk assessment, decision analysis, and subsequent software implementations. In addition to directing the development of the code he is also heavily involved in SADA education and training of SADA and the methods it uses. Robert as a M.S. in Mathematics and is currently completing his Ph.D. in Geography (GIS Systems) at the University.

Dr. Louis Gross
Co-Principle Investigator

Department of Ecology and Evolutionary Biology
University of Tennessee, Knoxville

Louis is Professor of Ecology and Evolutionary Biology and Mathematics and Director of The Institute for Environmental Modeling as well as the new National Institute for Mathematical and Biological Synthesis both located at the University of Tennessee in Knoxville. He has led the effort to develop an across trophic level modeling framework to assess the biotic impacts of alternative water planning for the Everglades of Florida. He is also well known for service on editorial boards of a variety of journals and being the organizer of over twenty conferences of professional societies. He is currently Past-President of the Society for Mathematical Biology and served as Chair of the National Research Council Committee on Education in Biocomplexity Research. He has served as Chair of the Theoretical Ecology Section of the Ecological Society of America. He has co-directed several Courses and Workshops in Mathematical Ecology at the International Centre for Theoretical Physics in Trieste, Italy, has edited or co-edited four books, including Individual- Based Models and Approaches in Ecology and Some Mathematical Questions in Biology: Plant Biology. In addition to his research in computational ecology, he has ongoing research projects in photosynthetic dynamics, landscape ecology, and the development of quantitative curricula for life science undergraduates.

Dr. Tom Purucker
Human health risk, ecological risk, & education

Ecosystems Research Division
National Exposure Research Laboratory
Office of Research and Development

Purucker.Tom@epamail.epa.gov; (706)355-8123

Tom has been instrumental in developing codes and methods for the human health and ecological risk models in SADA. He has also participated heavily in education and training on all aspects of SADA. Tom's Ph.D. is in ecology from the University of Tennessee and his more recent interests include: 1) Risks and benefits from biotechnology implementation, particularly the use of plant incorporated protectants in agroecosystems and indirect food chain effects; 2) Spatial estimation and agent-based movement models to estimate ecological exposure and effects from environmental toxicants; 3) Ecological risk assessment software library development to improve “production-level” ecological risk assessments through SADA and FRAMES software packages.

Dr. Christopher Welsh
University of Tennessee
Ecological risk, quality control, trainer

Fred Dolislager
Risk Assessment Manager; Trainer

The Institute For Environmental Modeling
University of Tennessee, Knoxville
1060 Commerce Dr. 
Oak Ridge, TN 37830

fdolislager@utk.edu; (865) 576-5451

Fred has been the principal contact for the human health risk assessment needs of SADA for 3 years and has been involved in the training team for SADA. Interests are in exposure modeling and risk-based decision making. Fred is also the Content Manager for the Risk Assessment Information System (RAIS) http://rais.ornl.gov/ and maintains 13 similar web-based tools for the US EPA spanning chemical and radiological risk issues. His extensive involvement with the RAIS and EPA risk assessment tools enable the SADA project to be instantly aware of any changes in US EPA guidance or toxicity values. Fred has a B.S. in Natural Science and 30 hours of graduate work at the University of TN.
