We develop and apply computational, statistical, and field methods to investigate subsurface fluid flow and solute transport in soils, aquifers, and geological reservoirs as well as their interaction with land-surface processes. While we work on techniques such as scaling theory, inverse methods, HPC, and AI, we also collaborate with geophysicists, geochemists, ecologists, and engineers to derive hydrological insights from multiple perspectives.

My teaching approach is one of thorough preparation, student participation, and individual mentoring. I set high expectations. All my courses emphasize the understanding of fundamental principles and their assumptions. The emphasis is on the understanding of concepts, theorems, and approaches

Sustainable water supply is critical to the semiarid western U.S. In Wyoming, mountainous watersheds receive approximately 60% of annual precipitation. Our aim is to improve water balance estimation for both headwater and downstream regions facing climate change and hydrological variability.
Carbon sequestration and enhanced oil recovery (EOR) have been proposed at many geological storage sites in the state's sedimentary basins. Our objective is to understand and reduce model uncertainty in simulating CO2 flow in geological formations characterized by sparse field and laboratory data.
Sedimentary basins are host to important natural resources (oil, gas, water). In the arid west, increasing attention focuses on the availability of freshwater and how to protect this limited resource. In the Rocky Mountain region, a significant problem is the salinization of rivers and groundwaters.
Uncertainties in modeling subsurface fluid flow and solute transport can be significantly reduced if the hydraulic conductivity (or permeability) heterogeneity is fully resolved.
Parallel computing has entered many science and engineering fields where large-scale problems can no longer be solved efficiently with serial computers/algorithms.

Please check my CV, under funded projects, for current research. Please read [Admission Information] and contact me if you have questions. Students with quantitative background, programming skills, and strong curiosity are encouraged to apply. Though GRE scores are not required by the Department, I will meet candidates on Zoom and administer my own exam to test math, logical thinking, and writing. After admission, graduate students are expected to excel in all courses I teach (under Teaching) and solve bonus, extra difficult problems. They are also expected to be resourceful and self-reliant.
