Research

My research in Geotechnical Engineering is mainly focused on the following areas:

  • Constitutive laws of geomaterials, with emphasis on anisotropy of sands and clays and the cyclic response of sands
  • Development of numerical methods, with emphasis on the developement of algorithms for stress integration of constitutive laws
  • Seismic ground response, with the development and use of numerical methods in 1, 2 and 3 dimensions
  • Element soil response, with emphasis on liquefaction and anisotropy of geomaterials
  • Ground improvement, with emphasis on seismic response of improved ground and liquefaction mitigation
  • Seismic micro-zonation studies, with emphasis on "intelligent" use of databases in conjuction with GIS
  • Seismic fault rupture, with emphasis on the rupture propagation through soil
  • Use of probabilistic methods, in issues of engineering seismology
