research

Our group researches physical hydrologic processes on the surface and in the subsurface of the earth. We integrate geophysical techniques, hydrologic measurements, and mathematical simulation to explore a wide range of processes including groundwater flow in porous media and fractured rock, contaminant transport, and groundwater-surface water exchange, as well as many interdisciplinary projects, some of which fall under the umbrella of critical zone science.

I admit students most years into the Hydrologic Science & Engineering Program. You can find more information on the program and admissions process here. Application materials are due December 15 to be considered for funding; I will note that funding is preferentially given to Ph.D. students, but we also will not admit Ph.D. students without funding available. If I have funding available, an opportunity will be posted below.

Students graduating from the Mines Hydrology Program have gotten great jobs all over the country, including jobs in academia, government (e.g., U.S. Geological Survey, the Bureau of Reclamation, Colorado Department of Public Health, Army Corps of Engineers, the Colorado Division of Water Resources, and multiple National Labs), and industry (Leppert, HydroGeoLogic, BGC, HRS, Leonard Rice, Itasca, Barr, Neptune, Jacobs, AECOM, Brown and Caldwell, TetraTech, and SSPA, among others I’m sure I’m forgetting).

If you’re interesting in working with me, please consider sending me an email with 1) a concise CV, 2) your background in brief, and 3) why you are specifically interested in working with me and/or at Mines. I’m not interested in your grades and test scores, but I am interested in evidence of your curiosity, team skills, communication, perseverance, and independence. Also, if you are thinking about applying to graduate school, check out this video on how to write a great application essay!

Below, I outline current and past multi-year projects of significant size; numerous other smaller projects are not listed here for brevity.
