H2/CO2 Storage · Porous Media Flow · Fluid Thermodynamics
I study how CO2 dissolves and moves through rock formations, research that directly informs the long-term safety of geological carbon storage.
PhD-trained researcher in CO2 storage and climate change mitigation, with expertise in multiphase flow, complex-fluid thermodynamics, and transport in porous media. My work integrates optical techniques, including shadowgraphy and laser-induced fluorescence, with X-ray computed tomography (CT) imaging to study convective dissolution and subsurface fluid dynamics. I am currently a postdoctoral researcher at UPPA’s DMEX lab, where I investigate the convective dissolution of CO2 in reservoir rocks for CO2 storage applications.
Research Projects
Convective Mixing
Experimental and numerical study of CO2 dissolution driven by density differences in porous media.
Ongoing
X-ray CT
Using X-ray tomography to directly image fluid flow and CO2 dissolution inside model and natural porous media.
Ongoing
Porous Media Flow
Investigating multiphase flow behaviour in porous rocks to understand how fluids move and interact at the pore and core scale.
Ongoing
Thermodynamics
Measuring equilibrium and transport properties of CO2 mixtures under high-pressure subsurface conditions.
Ongoing
Hydrodynamic Fluctuations
Probing non-equilibrium fluctuations in complex fluids using optical techniques to extract diffusion coefficients.
Ongoing
