My research work focuses on three-dimensional imaging of multiphase flow in permeable media using both in-house and synchrotron X-ray micro-CT, with applications to geological sequestration of CO₂, remediation of contaminated soils and oil recovery from reservoirs.

Current projects

(i) Pore-scale dynamics of immiscible fluid displacement in porous media using ultrafast synchrotron X-ray micro-tomography.

(ii) Effect of wettability on flow in porous media (including high pressure and elevated temperature experiments).

(iii) Multi-scale characterisation of carbonate rocks (including dissolution during supercritical CO₂-saturated brine injection): FIBSEM, Confocal and X-ray micro-tomographic imaging.

Other curiosity-driven projects

(i) Architectural design of smart ventilation and drainage systems in termite nests.

(ii) Three-dimensional microstructure of lignocelluloses and their implications for the performance of the catalytic upstream biorefining.
