Research Experience and Interests
Robert’s interests center around quantitative and computational methods geospatial and spatiotemporal modeling, with an emphasis on stochastic methods in uncertainty, risk, and decision analysis. Areas of application have primarily centered on environmental pollution, risk, sample design, remediation, and associated implications for regulatory compliance. Recent activities include other geographical sciences such as population dynamics and spatial epidemiology. Quantifying uncertainty and risk as well as understanding the implications of both for decision making is a recurring theme in the work.
In addition to his work here, Robert is holds the position of joint faculty assistant professor in the Geography department at the University of Tennessee where he also collaborates with The Institute for Environmental Modeling. Robert leads development and collaborations between UT and ORNL on the Spatial Analysis and Decision Assistance (SADA) project. The focus of this project is the SADA freeware package that integrates many of the themes previously mentioned.
