Biography

Liange Zheng is a Staff Scientist and the Nuclear Energy and Waste Program Head in the Energy Geosciences Division at Lawrence Berkeley National Lab. His research interests, which are centered on numerical modeling of non-isothermal, multiphase flow and multi-component reactive transport in porous media, and also include the inverse methodologies of parameter estimation, and coupled modeling of thermal (T), hydrodynamic (H), mechanical (M) and chemical (C) processes in the subsurface. During his Ph.D. work at the University of La Coruña, Spain, Liange conducted numerical simulations of geochemical evolution and corresponding thermo­-hydro­mechanical processes in various porous media in the context of performance assessment of geological repositories for radioactive waste. His research work at LBNL is related to CO₂ geological sequestration, radioactive waste disposal and enhanced geothermal system (EGS). He has been working extensively on the study of the impact of  CO₂ leakage on groundwater, focusing the potential release of trace elements in the shallow aquifer, the mobilization of  organic compound by supercritical CO₂ and the effect of co-injected acid gas (i.e., H₂S) on groundwater quality. He is also working on simulating the couple THMC processes in the engineering barrier system (bentonite) and host clay rock for radioactive waste disposal system and developing a new analytic-adaptive model for EGS assessment.
