PhD Assistantship (Flow and Transport in Porous Media) via AGU

University of Arizona

Tucson, AZ, United States 🇺🇸

Dr. Bo Guo’s Subsurface Flow Physics Group ( has one opening for a fully-funded PhD student starting in Fall 2021 through the Department of Hydrology and Atmospheric Sciences (HAS) at the University of Arizona (UA). Successful candidates would have the opportunity to work on one of the following research directions:

(1) Fate and transport of emergent contaminants in soils and groundwater.

(2) Physics of nano-scale fluid flow, transport, and thermodynamic phase behavior relevant to sustainable unconventional shale gas/oil recovery.

(3) Reactive transport modeling of the biogeochemical processes in the critical zone.

Our group studies the fundamental physics of fluid flow and transport in Earth’s subsurface. We develop and use novel mathematical and computational models to understand and quantify flow and transport processes in geological porous materials across a wide range of spatial scales from microscale (i.e., pore scale) to laboratory scale and to real-world subsurface environmental and energy problems at the field scale. Specific application areas of our research include contaminant transport in soil and groundwater especially emerging contaminants such as PFAS, critical zone science, shale gas/oil recovery, and geological CO₂ sequestration. Students with bachelor’s and/or master’s degrees in hydrology, applied mathematics, civil engineering, mechanical engineering, and other closely related fields are encouraged to apply. Candidates with a strong background in mathematics, fluid mechanics, and computation are especially welcome.

To apply, please contact Dr. Guo ([email protected]) to discuss potential research projects and opportunities. When contacting via email, please include the following materials: unofficial transcripts, curriculum vitae, and a brief summary that highlights your skills and research interests relevant to Dr. Guo’s research. All applicants should meet the minimum admission requirements ( set by the Graduate College at the UA. The application deadline is January 15, 2021.

Dr. Guo is an Assistant Professor in the Department of Hydrology and Atmospheric Sciences at the UA. He received his PhD in Civil and Environmental Engineering from Princeton University in 2016 and a bachelor’s degree (with highest honor) in Hydraulic Engineering from Tsinghua University in 2011. Before joining the UA, Dr. Guo was a postdoc in the Department of Energy Resources Engineering at Stanford University.

The UA HAS department ( has one of the most prestigious programs in hydrology and water recourses worldwide. It was previously known as the Department of Hydrology and Water Resources, which was the first department in the US (established in 1966) dedicated solely to the science of water. The UA water resources program has always been top-ranking in various university ranking systems. For example, the UA ranked No. 1 in the U.S. and No. 2 globally in the area of water resources in the 2020 Academic Ranking of World Universities. To learn more, please see
