Robert N Stewart

Group Lead for Geographic Data Sciences

I am presently the group leader for the Geographic Data Sciences 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 spatio-temporal modeling, with an emphasis on uncertainty, risk, and decision analytics. Areas of application include population dynamics, socio-cultural/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.
