Randal Barnes' research interests traverse mathematical modeling in geological and civil engineering. His recent research work is comprised of three interacting focii. The first research focus is geostatistical site characterization: specifically, optimal sample design and engineering decision-making in the face of spatial variability and parameter uncertainty. The second is the incorporation of uncertainty into quantitative modeling for geoengineering. The third, and most recent, focus is the development and extension of computational aspects of the Analytic Element Method in geoengineering.
