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

Current projects

(i) 3D imaging of hydrogen storage in reservoir rocks

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

(iii) Effect of wettability on multiphase flow in porous media

(iv) 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.
