The overall goal of my research is to study and understand reactive, multiphase transport in porous media. I am particularly interested in understanding and manipulating chemical and physical processes that occur during reactive, multiphase transport in both engineered (cementitious) and natural (geological) porous materials. To this end, I use quantitative imaging approaches such as X-ray computed tomography (CT), neutron tomography, and electrical imaging modalities which provide digital representation of a material to feed computational models in our digital age. I am interested in using hybrid and simultaneous imaging modalities because complementary temporal information can be obtained using these approaches to better understand complex processes in porous materials. The broader impacts of this research include Carbon Capture and Storage (CCS) well integrity and climate change mitigation through composite material characterization and development. Ensuring CO2 is sequestered efficiently and remains trapped below ground is essential for both environmental and economic reasons as well as human health.
