Fields of Research

  • Durability of reinforced concrete structures
  • Concrete materials
  • Corrosion of metals

Researcher Summary

Primary research is related to understanding the influence of material properties and environmental conditions on the durability of reinforced concrete structures, and the development of durability models to assist in the prediction of service life and the optimization of repair strategies. Other research interests include stress corrosion cracking and flow assisted corrosion of pipes under conditions of high flow, temperature and varying environmental conditions.
