Research interests

Today the world builds at an unprecedented pace. Construction industry is responsible for about 40% of the worlds carbon footprint. To reduce it, it is desirable to first, keep existing structures in service as long as possible, and second to design new structures to be recycleable or with a long life. The challenge here is how do we find the balance between the safety of the structures, the costs of making and using them and the impact on our environment. My work’s aim is to promote sustainability in the construction industry through sustainable-conscious structural design. 

My objectives are to:

  • develop methods to predict the life span of existing structures, 
  • provide solutions to extend their life when needed and 
  • quantify the impact of different decisions on the life length of a structure.   

Professional expertise

  • Design and assessment of concrete structures
  • Strengthening of concrete structures using FRPs
  • Non-linear finite element modelling
  • Structural Health Monitoring
  • Management of research and industrial projects
