Education

• PhD in Structural Engineering, Cambridge University.
  Thesis title: Performance of a Composite Space Truss Bridge with GRP Panels. 1996
• BA in Civil Engineering (MA 1993), Cambridge University. 1989

External Recognition

• Examiner for research theses at Bradford, Cambridge, Glamorgan, Heriot-Watt and Southampton universities.
• Editorial panel member for Structures and Buildings journal of UK Institution of Civil Engineers.
• Election to peer-review college for UK’s Engineering and Physical Sciences Research Council (EPSRC).
• Invited member of four EPSRC panels to rank proposals up to £1.2 million.
• Reviewer of papers for leading international journals including the ASCE Journal of Structural Engineering, the Engineering Structures journal and the International Journal of Solids and Structures.
• Commissioned by UK Highways Agency to pursue full-scale fatigue study into composite bridge decks.
• Member of UK panel set up to produce documents for guidance on design, installation, monitoring, inspection and maintenance of composite reinforcement of concrete structures. Documents are globally recognised ; e.g.one was used to design composite strengthening associated with the Westgate bridge in Australia.

Research

• Fatigue of bridges with decks fabricated from fibre reinforced polymer advanced composite materials.
• Short-term and long-term (creep) behaviours of structures and materials.
• Hyperstatic structures from zero load through elastic and elasto-plastic stages to (plastic or other) failure.
• Advanced nonlinear finite element computations for structural analysis.
• Iterative computational techniques for time-efficient optimisation of structures.
• Buildings and bridges incorporating eco-friendly materials and fabrication procedures.
• Hybrid structures including effects of mechanical or chemical interface connections.
• Large-scale testing coupled to advanced analysis.
