Dr. Jeff Fitts is a Research Scholar, in the Civil and Environmental Engineering department at Princeton University. His research combines numerical, experimental, and material structure probes to study chemical reactions at interfaces that drive the evolution of environmental systems. The aim is to advance the Geochemical Science and Engineering needed to develop increasingly robust quantitative projections of the human health, environmental and climatic costs of energy technologies. Synchrotron-based x-ray probes are often applied to study dissolution, precipitation and contaminant speciation at mineral-water interfaces. Current projects aim to assess contaminant mobility during shale gas extraction, permeability evolution of leakage pathways through caprocks of geologic CO2 storage reservoirs, stability of encapsulated nuclear waste, and activity of catalysts for wastewater treatment. He has published dozens of articles in peer reviewed journals.
