Research Statement

(1) Parameter Estimation

Permeability heterogeneity is the single most salient feature of sedimentary aquifers. It exerts a dominant control on subsurface fluid flow and solute transport, while the lack of its representation in hydrogeological models accounts for much uncertainty in model predictions. In lieu of heterogeneity, models adopt effective parameters to represent the bulk flow/transport behaviors arising out of the unresolved heterogeneity. To address the issues related to "the heterogeneity problem", my research focuses on (a) innovative data; (b) new upscaling method; (c) high performance computing; (d) novel statistical analysis technique.

 

(2) Regional Hydrogeology

In the hydrocarbon-rich intermontane basins of the Rocky Mountain region, little is understood of the interplay of groundwater flow, salinization, and petroleum generation/migration. At the basin scale, groundwater flow is coupled to heat transfer and salinity transport (variable-density flow). The data-rich Uinta Basin in Utah provides a natural laboratory to understand a variety of subsurface phenomena. My research focuses on (a) realistic 3D model building; (b) regional 3D mapping of water and gas chemistry; (c) geostatistical modeling (CoKriging) to predict gas concentration/migration pathways; (d) based on field sampling, theoretical analysis on fluids co-migration via multiphase flow modeling.

 

(3) Mountain Hydrology

Sustainable water supply is critical to the semiarid western U.S. In Wyoming, mountainous watersheds receive approximately 60% of annual precipitation and are sources for downstream water supplies. Groundwater in mountains however is poorly known, due to lack of characterization and monitoring data. Funded by NSF EPSCoR and Wyoming Water Development Commission, we drill, test, monitor, and characterize an interconnected hydrological system centered at Laramie Range, Wyoming, and its mountain front areas: (1) Casper aquifer in Laramie Basin receiving runoff from the western Range; (2) Blair Wallis Fractured Rock Research Well Field in the Range; (3) Casper aquifer in Denver Basin receiving runoff from the eastern Range. At these sites, we monitor water level and temperature of streams and bedrock wells. At Blair Wallis, we conduct hydraulic well tests at a variety of scales and work on joint analysis of hydrological and geophysical measurements to ''look into the subsurface''. Our aim is to improve water balance estimation for both headwater and downstream regions facing climate change and hydrological variability.

Teaching Statement

My teaching approach is one of thorough preparation, student participation, and individual mentoring. I use both mathematical models and hands-on exercises to clearly illucidate the concepts, theories and their applications. Though mathematical rigour in developing the models is an integral part of the instruction, practical applications and appropriate use of models are also emphasized. Thus, most of the exercises, howework and projects involve solving practical hydrogeological problems either by hand or by computers (more advanced classes only). I emphasize to the students the importance of being professional at this early stage of their career, by encouraging critical thinking, logical and clear writing, and quantitative rigour. In general, I assist students to “learn how to learn” and solve problems independently. For complex projects, students are sometimes encouraged to work in groups and to seek solutions in a collaborative environment, as team work is key to success in many real-world situations.
