Dr Roberts specializes in hydrochemistry and microbial geochemistry, bridging basic and applied science and focusing on the role of microorganisms on mineral chemistry and weathering as it applies to carbon sequestration, petroleum reservoir diagenesis, paleoclimate, and water quality from the nano- to landscape scales.

I teach introductory geology, geomicrobiology, ethics and a range of specialty courses in at the intersection of energy and environment.
My research program focuses broadly on microbe:mineral interactions and the geological and ecological implications of these interactions in subsurface environments. My program currently has three separate but interrelated thrusts—microbial attachment to mineral surfaces; nutrient-driven microbial silicate weathering, and low temperature-dolomite precipitation.
