Biography

Hang Deng is a post-doc fellow in the EFRC for the Nanoscale Control of Geologic CO₂, with research expertise in environmental geochemistry and hydrogeology. Her research has been focusing on water-rock interactions and the resulting evolution of the geometries and hydraulic properties of fractured porous media, and the implications to real world practices such as subsurface technologies and engineering. In her current research projects, she develops and applies reactive transport models that integrate small scale processes/phenomena to investigate and predict the impacts of coupled flow, transport and reactions in fractured porous media under conditions relevant to geologic CO₂ storage. Hang received her PhD in Civil and Environmental Engineering from Princeton University, where she worked on geochemical alterations of fractures and the environmental and policy implications. Her PhD projects include (1) the development of novel image processing techniques for fractured porous media characterization using computed tomography, (2) the development of mm- to cm- scale high pressure core-flooding experiments for the investigation of the role of mineralogy and fluid chemistry in controlling water-rock interactions, (3) the application of Computed Fluid Dynamics (CFD) simulations and reactive transport modeling to quantify and predict the dynamic evolution of fracture hydraulic properties caused by complex geochemical alteration, and (4) the evaluation of the economic viability of carbon mitigation technologies, such as Carbon Capture and Sequestration (CCS), using Integrated Assessment Models (IAMs).
