Research interests

My main research interest is computational mechanics. 

I have been working on constitutive modelling of sand accounting for the effect of anisotropy and evolution since 2009. The constitutive model has been used for finite element modelling of practical boundary value problems. This research has shown that anisotropy should be properly considered in calculating the bearing capacity of shallow foundations because an isotropic model can give significant overestimation. 

I have worked with QTS (https://www.qtsgroup.com/) to develop a design for lightweight rock catch fences through laboratory tests, finite element modelling and full-scale field tests. This project was funded by the Knowledge Transfer Partnership (KTP) of Innovate UK. Based on the outcome of this project, a remote monitoring system was developed with funding from Construction Scotland Innovation Centre (CSIC). The KTP Associate Dr Hassan Al-Budairi is now working at QTS as a Research and Development Engineer (https://www.linkedin.com/in/hassan-al-budairi-179bbaa4/?originalSubdomain=uk).

I am currently working on geotechnical problems associated with climate change and finite element modelling of offshore wind turbine foundations. I have developed a new composite method for constitutive modelling of gassy clay. Papers have been published in Can Geotech J and NAG. I am now working with Dr Nabil Sultan on multiphysics modelling of gas migration in clay, with the support of The Royal Society. I am also working with Geowynd (https://geowynd.com/) on finite element modelling of offshore wind turbine foundations in sand (https://www.linkedin.com/posts/geowynd_ocean-project-summary-activity-6842029865479352320-Gjbu). The project is funded by the Royal Academy of Engineering.

Teaching

  • ENG4070: Geotechnical Engineering 4: This is a course for BEng, MEng and MSc students. I was the course convenor for one year. This course has included content on site investigation, ground improvement and pile foundations.
  • ENG4072: Ground Engineering 4: This is a course for BEng, MEng and MSc students. The main content includes: finite element modelling in ground engineering, time-dependent soil response and basic knowledge of unsaturated soil mechanics.
  • ENG4188: Geotechnical Design Project 4: This design project is for MEng students. It is based on a brief for a road embankment and bridge abutments on soft clay, with the embankment height varying across the site, ground conditions based on real site investigation data and various other site constraints. Students work in groups and consider the behaviour of the embankment firstly with no ground improvement and secondly with various forms of ground improvement, with the objective of developing a design for the embankment and the bridge abutments.
  • ENG3986: Transportation Engineering 3: This is a course for BEng, MEng and MSc students on transportation design. It includes the inclusivity of transportation networks, design for walking, cycling and motorways.
