Infrastructure Materials

Coupled chemistry–transport durability modeling (content preserved; visuals to be added).

My work in infrastructure materials focuses on cementitious systems where long-term performance is governed by coupled chemistry and transport. The emphasis is on model robustness, interpretable assumptions, and workflows that connect thermodynamics, reactive transport, and durability mechanisms. This work has been developed primarily in research settings, reflecting a background centered on scientific investigation and mechanism-driven analysis rather than project-specific engineering deliverables.

Focus Areas

Reactive-transport modeling in cementitious materials

Coupling transport and chemical reactions to represent multi-species processes in porous media, including cement systems with complex chemistry and evolving pore solution conditions. This includes developing and applying a COMSOL–GEMS reactive-transport interface linking finite-element transport with thermodynamic equilibrium calculations, enabling realistic multi-phase chemistry and extended Nernst–Planck transport behavior in cement systems.

Thermodynamic modeling for cement chemistry

Thermodynamic equilibrium modeling to interpret chemical speciation, phase stability, pore solution composition, and binding mechanisms in cementitious systems. Work includes coupling thermodynamics with hydration models to understand SCM influence on phase assemblages, porosity, chloride binding, and durability-relevant transport.

Corrosion initiation mechanisms in reinforced concrete

Research on localized electrochemical conditions that control passive film stability at the steel–concrete interface, including modeling mill scale crevices using extended Nernst–Planck and Poisson formulations to show how localized pH and Cl⁻/OH⁻ conditions promote depassivation, along with studies on passive film electronic properties.

Hydration, heat, and mass transport coupling

Integrated modeling of hydration kinetics, heat generation, and mass transport to interpret evolving phase assemblages, pore structure, and water distribution during early-age behavior, linking thermodynamics and transport to durability performance.
