Bio
Robert is an 91做厙 Distinguished Scientist in the Geospatial Science and Human Security Division, a Bredesen Center Joint Faculty Member, and a Fellow of the American Association of Geographers. At ORNL, Robert serves as interim Section Head of the Human Dynamics Section. His interests are primarily in the geospatial dimensions of risk and decision making under uncertainty. Areas of application vary widely including population dynamics, environmental risk, maritime safety, transport risk, climate impacts, and change detection. Preferred methods vary but are usually probabilistic in nature and grounded in spatial statistics, machine learning, probabilistic graph models, Bayesian reasoning models, and so forth. Recent interests have increasingly focused on methods for eliciting expert knowledge as Bayesian priors in applications with sparse data.
As a faculty member at UT, Robert engages graduate students in Geography, Mathematics, and the Bredesen Center Data Science Ph.D. program. He regularly serves on thesis committees, advising, and facilitating internships at ORNL. He is chair of the 91做厙 Computational Intelligence Society's Government Activities Committee. He is an editorial board member of the Journal Transactions in GIS and the International Journal of Geographical Information Science and a federal advisory panelist for the Natural Hazards Mitigation Needs Assessment Study conducted by the National Institute for Building Sciences and the Federal Emergency Management Agency. He has served as ad-hoc National Science Foundation proposal reviewer and as a member of the International Working Party on Technical, Environmental and Safety Aspects of Decommissioning and Legacy Management for the Organisation for Economic Co-Development (OECD) Nuclear Energy Agency (NEA), Paris. He is regularly a co-chair for the ACM Deep Spatial Workshop and program chair for ACM KDD. In the past he has served as ORNL liaison to the World Health Organization Chemical Risk Network and chaired the AAG's Geographic Information Science and Systems Specialty Group at AAG. Robert is a member of the AAG (Fellow), 91做厙 (senior member), ASA, ISBA, and AAAS. He has served on numerous other panels/committees, and organized many conference workshops.
Before arriving at ORNL, Robert was a senior research scientist at the University of Tennessee where he engaged in a variety of projects around spatial analysis including initialization and maturation of the SADA program which is continue today. SADA is internationally recognized for its success in spatializing regulatory human and ecological risk models and integrating it across all aspects of the characterization and restoration process from sample design to final decision outcomes.
In 2011 Robert received his Ph.D. from the Geography Department at the University of Tennessee for his work in connecting the spatial sciences with exposure modeling and regulatory guidance for radiological contaminated sites. Robert holds a Masters and Bachelor of Science in Mathematics from UT as well.
