About

Research topics:

  • Various projects concerning soil modelling. This includes:
    • Modelling and understanding creep in soft clays and other aspects of soil behaviour.
    • Development and implementation of a number of soil models, including the NGI-ADP model that is now part of a commercial finite element program (www.plaxis.nl).
  •  Progressive failure in sensitive clays. This includes:
    • Work with the implementation of a regularisation technique for modelling of brittle material behaviour in finite element calculations
    • Back calculations to landslides involving quick clay
