Engineering
Civil and Environmental Engineering

My area of research is multidisciplinary with aspects of applied mathematics, petroleum engineering, computer science, and fundamental physics. My research integrates these disciplines into a comprehensive framework for digital materials characterisation, porous media imaging and modelling, and multiphase flow studies related to future energy technologies.

Applications include digital rock physics, in situ recovery of minerals, geological storage of hydrogen, recovery of transition fuels, geological storage of CO2, mineral liberation analyses, and machine learning in resources engineering.
