Curriculum Vitae

Biography

I am currently a Research Scientist in the Energy Geosciences Division at the Lawrence Berkeley National Laboratory (LBNL). I received a B.Eng. in Geological Engineering in 2010 and a Ph.D. in Hydrogeology in 2016. My research focuses on the experimental studies of reservoir processes and subsurface hydrology in porous and fractured media, including multiphase flow, phase dissolution and mass transfer, interfacial and wetting phenomena, carbon dioxide sequestration and shale gas. At LBNL, I work on (1) nanomaterial synthesis and application for investigating subsurface energy production (oil & gas, geothermal, etc.); (2) pore-scale supercritical CO₂-brine displacement, including mass transfer and interfacial wetting effects under reservoir high pressure and high temperature conditions, using 2D micromodels, facilitated with fluorescent tracer dye and microscope imaging; (3) core-scale multiphase flow and rock mechanics with X-ray CT imaging and customized triaxial loading system, (4) bench-scale investigations of coupled THMC processes in engineered (clay) barrier systems and engineered (bedrock) damage zones for ensuring the safe and long-term performance of geological disposal of spent nuclear fuel and waste.

Research Interests

My primary research interests and expertise are in experimental studies of reservoir processes and subsurface hydrology in porous and fractured media, including multiphase flow, phase dissolution and mass transfer, interfacial and wetting phenomena, rock mechanics and coupled THMC fundamentals. These experimental studies are motivated by the need to better understand processes controlling geological CO₂ sequestration, spent nuclear fuel and waste disposal, shale gas & oil, and geothermal energy production. At LBNL, I work on (1) nanomaterial synthesis and application for investigating subsurface energy storage and recovery; (2) pore-scale supercritical CO₂-brine displacement, mass transfer and interfacial wetting effects under reservoir high pressure and high temperature conditions in microfluidic devices, facilitated with fluorescent tracer dye and microscopy; (3) core-scale fracture-matrix multiphase flow and mass transfer with X-ray CT imaging and (4) bench-scale investigation of coupled THMC processes in engineered (clay) barrier systems and engineered (bedrock) damage zones in geological disposal of spent nuclear fuel and waste. My other interests include approaches to quantitatively describe and characterize permafrost core using multi-energy CT scanning.
