I studied civil engineering at the University of Sydney, and did my doctorate here at Oxford. Before deciding to embark on an academic career, I spent several years in industry, designing offshore structures for the consulting engineering firm Ove Arup & Partners. After three years as a Research Fellow at the University of Western Australia, I returned to Oxford as a University Lecturer (and Fellow of Mansfield) in 2000. My main research interests are in the theory of plastic material behaviour, as used in the analysis and design of geotechnical structures (foundations, retaining walls, tunnels) and steel and concrete structures (portal frames, plates, slabs). I also have interests in soil-structure interaction, particularly offshore problems such as the stability of mobile drilling platforms and wind turbines, and thermally-induced buckling of subsea pipelines. I am a member of the Civil Engineering Research Group in the Department of Engineering Science, and my homepage is here.
