research
Our group works on a variety of projects with a focus on physical hydrologic processes on the surface and in the subsurface of the earth. We integrate geophysical techniques, hydrologic measurements, and mathematical simulation and have looked at a wide range of processes from fracture flow to vadose zone infiltration, contaminant transport, groundwater-surface water exchange, and groundwater-evapotranspiration connections. Additionally, we have worked on a number of interdisciplinary projects, including linking water quality degradation and human behavior, imaging moisture dynamics and their link with ecosystems, exploring changes in infiltration after fire, and quantifying subsurface controls on water movement in the Arctic.

I admit students most years into the Hydrologic Science & Engineering Program. Application materials are due December 15 to be considered for funding; I will note that funding is preferentially given to Ph.D. students such that not all MS students can be funded, and it is always hard to predict when funding is available. In general, I do not have funded projects waiting for students--I usually recruit quickly when grant money becomes available. You can find more information on the program and admissions process here.

Below, I outline current and past multi-year projects of significant size; numerous other smaller projects are not listed here for brevity. All projects here have students already working on them unless noted otherwise.
