Dr. Tissa H. Illangasekare (Colorado School of Mines, USA).

Dr. Illangasekare has improved the fundamental understanding of fluid flow and chemical transport in porous media through innovative multi-scale experimentation and modelling, leading to the reliable prediction of the long‐term fate of pollutants in groundwater systems and the behaviour of multiple phase fluids in shallow and deep geologic formations.

His research on the fundamental understanding of the behaviour of multiphase fluids in heterogeneous porous media has addressed issues of the permanent storage of CO2 in deep geologic formations, with a focus on the trapping of CO2 and potential leakage to shallow aquifers. His work addresses the mathematical modelling of multi-phase flow, the effect of geologic heterogeneity in enhancing capillary and dissolution trapping of supercritical CO2, and a benchmark modelling study of CO2 gas evolution in groundwater systems.
