Graduate Program in Applied Mathematical and Computational Sciences. Dr. Armstrong’s Ph.D. is from the University of Illinois at Urbana-Champaign. A primary focus of his research is on the use of parallel processing to improve the performance of analysis methods used in spatial decision support systems. Other active areas of interest are in mobile computing, privacy aspects of geospatial technologies, and evolutionary computation. Dr. Armstrong has served as North American editor of the International Journal of Geographical Information Science, associate editor of Cartography and Geographic Information Science, co-director of Auto-Carto 11, and conference chair for GIS/LIS ’94. He now serves on the editorial boards of the International Journal of Geographical Information Science, Cartography and Geographic Information Science, and Geographical Analysis. Dr. Armstrong has published more than 100 academic papers including articles in a wide variety of peer-reviewed journals such as Annals of the Association of American Geographers, Environment and Planning A, B & C, Photogrammetric Engineering and Remote Sensing, Geographical Analysis, Geographical Systems, Journal of the Urban and Regional Information Systems Association, Statistics and Medicine, Mathematical Geology, Computers & Geosciences, International Journal of Geographical Information Science, Computers, Environment and Urban Systems, and Journal of the American Society for Information Science.

Budhendra L. Bhaduri is leader of the Geographic Information Science and Technology Group in the Computational Sciences and Engineering Division at Oak Ridge National Laboratory. He holds a Ph.D in earth and atmospheric sciences from Purdue University, M.S. degrees in geology from Kent State University and the University of Calcutta, India, and a B.Sc. with honors in geology from the University of Calcutta. Dr. Bhaduri conceives, designs, and implements innovative computational methods and simulation algorithms to solve a variety of problems in land cover modeling, natural resource management, emergency management, and transportation studies using geographic information system and image analysis techniques. Current projects include LandScan and LandScan USA (a high-resolution population distribution and population dynamics model and database); a systems-level model for advanced geospatial technologies using large-scale spatial data from the Tennessee Base Mapping program; an Image-to-Intelligence Archive for large-scale image databases; and a project to enhance intelligent consequence management with evolving spatial technologies. Dr. Bhaduri has published widely in the academic literature, provided technical reviews for a number of scientific journals, and is a lead theme writer on the first National R&D Plan for Critical Infrastructure Protection, Department of Homeland Security, Science and Technology Directorate.
