Robert is a Distinguished Scientist in the Geospatial Science and Human Security Division at the Oak Ridge National Laboratory (ORNL) and joint faculty member of the Bredesen Center and Geography Department at the University of Tennessee. Roberts leads projects engaged in a wide array of R&D including spatial probability modeling, computational statistics, spatio-temporal analytics, data mining, big data workflows, simulation, and tool development. HIs work is informed by and applied to a wide range of use cases emerging from population dynamics, maritime safety, geomatics, urban dynamics, security, energy-water nexus, health, environmental risk and many others. His own research is focused on statistical and computational methods in the areas of spatio-temporal analytics, probability modeling, and uncertainty quantification with an emphasis on risk and decision support. As a joint faculty, Robert engages graduate students in geography, mathematics, and others. He regularly serves on thesis committees, advising, and facilitating internships at ORNL. Robert is also the chair of the IEEE Computational Intelligence Society's Government Activities Committee, an editorial board member for the International Journal of Geographical Information Science, the journal Transactions in GIS, and a delegate to the OECD Nuclear Energy Agency's Working Party on Technical, Environmental and Safety Aspects of Decommissioning and Legacy Management. He is also an advisor to the Alan Turing Institute's Colouring Cities Research Programme.
