Robert N. Stewart
I am geographic data scientist in the Geographic Information Science and Technology (GIST) group at the Oak Ridge National Laboratory and a joint faculty assistant professor in Geography at the University of Tennessee. My work is focused on statistical and computational methods in the areas of spatial and spatiotemporal modeling, with an emphasis on uncertainty, risk, and decision analytics. Areas of application include population dynamics, sociocultural/economic analytics, social media, and environmental risk. Quantifying uncertainty and risk as well as understanding the implications of both for decision making is a recurring theme in my work. I currently serve as team lead for the Geographic Data Sciences Team within the GIST group.
