Research interests

My main research interest is the constitutive modelling of soils. I have developed constitutive models for sand anisotropy and used them in finite element modelling of practical boundary value problems. The research has shown that anisotropy can cause strain localisation and anisotropy should be considered in calculating the bearing capacity of shallow foundations. I have also developed a new composite method for the constitutive modelling of fine-grained soils containing discrete gas bubbles (gassy clay). Papers have been published in the Can Geotech J and NAG. One publication was the 2022 Can Geotech J editor's choice paper: A critical state constitutive model for gassy clay.

I have collaborated with QTS to develop a design for lightweight rock catch fences, with funding from the Knowledge Transfer Partnership (KTP) of Innovate UK. We have also designed a new remote monitoring system with the support of the Construction Scotland Innovation Centre (currently Built Environment – Smarter Transformation). Both the new catch fence and monitoring system have been deployed by QTS in railway projects in the UK.

I have worked with Geowynd on finite element modelling of offshore wind turbine foundations in sand. The project was funded by the Royal Academy of Engineering Industrial Fellowship. A new method for modelling the cyclic response of monopiles has been developed and published in Computers and Geotechnics.

Teaching

  • ENG5284: Advanced Soil Mechanics 5: This is a course for MEng and MSc students. The course covers basic principles of constitutive modelling, critical state theory and the Cam-Clay models.
  • 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 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, to develop a design for the embankment and the bridge abutments.
  • ENG3086: Transportation Engineering 3: This is a course for BEng, MEng and MSc students on transportation design. It includes the inclusivity of transportation networks, and design for walking, cycling and motorways.
  • ENG3073: Geotechnical Engineering 3: This course is for BEng, MEng and MSc students. Content includes the consolidation, drained/undrained analysis, soil behaviour in shear and critical state soil mechanics.
  • ENG3076: Civil Design Projects 3: This is a design project for Year 3 students. I am delivering the second part related to geotechnical engineering. Students are required to carry out a geotechnical design for a railway platform extension and embankment stabilisation using their knowledge learnt in Geotechnical Engineering 3.
