My research focuses on multiphase flow in porous media, which is essentially how multiple fluids move through materials filled with tiny, interconnected spaces. These materials are found everywhere: from the earth beneath our feet, to the tissues in our bodies, and the materials in our infrastructure. Specifically, I work on upscaling problems, by utilizing methods like pore-scale modeling, thermodynamics, and statistical physics. Additionally, I work on fiber bundle models and percolation theory, with particular attention to the relationships between disorder, connectivity, structure, and failure mechanisms. My academic background includes a PhD in statistical physics.
