We develop and apply numerical, statistical, and field-based methods to investigate subsurface fluid flow, solute transport, and chemical reactions in soils, aquifers, and deep reservoirs. We work on techniques ranging from scaling theory, inverse methods, high performance computing, to hydrogeophysics. Research topics include aquifer characterization and modeling, surface/groundwater interaction, and issues related to subsurface energy storage. Since 2014, we've been drilling and testing wells in the Laramie Range and surrounding mountain front areas in southeastern Wyoming with the objectives of advancing the science of mountain hydrology and mountain front recharge. Funding comes from the US National Science Foundation, Department of Energy, American Chemical Society (Petroleum Research Fund), Wyoming Water Development Commission, and the School of Energy Resources at the University of Wyoming. We collaborate with scientists and engineers at Los Alamos National Laboratory, Schlumberger, Colorado School of Mines, and at UW. Computing resources we access include laboratory PCs, parallel clusers[ARCC], and supercomputers[NWSC].
