My research focuses on cementitious grouting in Tunnel Boring Machine (TBM) technology. It emphasises how cement particle filtration, permeability reduction, and time-dependent grout rheology govern transport in porous and fractured media.

I am developing a coupled numerical modelling framework that links two-phase grout–water displacement, evolving non-Newtonian rheology, and filtration-induced clogging in both low-permeability soils and fractured rock.

The goal is to move beyond empirical grouting rules by deriving physics-based stop criteria, thereby improving penetration prediction, reducing grout and energy consumption, and enabling more reliable pre-excavation grouting design for TBM projects.
