After a short spell in industry, I joined the University of Warwick in 1986, where I am based to this day. I am a Professor in the School of Engineering, University of Warwick, a chartered engineer, and a Fellow of the Institution of Civil Engineers. My 30+ years of research experience is reflected in the monograph 'Tension Structures: Form and Behaviour' (review), numerous research articles and technical press. Having studied tension structures extensively, I learnt about the importance of structural form and a process of form-finding in which a structure is shaped by forces applied to it. This ‘form follows force’ feature is observed in the formation of natural objects. Aspects of my work on structural form and biomimicry in form-finding are reflected in documentaries (listed under Public Engagement), podcasts, and press releases.
My work on computational form-finding of flexible fabric structures progressed to analytical form-finding that predicts optimal shapes of rigid structures, such as arch bridges, for example. This work challenges conventional design approaches that use imposed structural forms and rely on the limit state design philosophy alone.
I have led a number of national and European research projects in collaboration with industry (Arup, Jaguar, Roll-Royce, SL-Rach, Canobbio) as well as multi-disciplinary projects, such as 'Designing for the 21st Century' - in collaboration with the Courtauld Institute of Art, London.
General research is concerned with FORM-FINDING: Conceptual Design of Fabric Structures, Minimal Structures and Nature, Structural Form in Engineering, Nature and Art. The essence here is to achieve an optimums structural forms by using nature’s own design principle that ensures minimal minimal response to statistically prevalent loading. As stated in the Background, work on the design of natural structural forms goes beyond flexible tension structures and includes rigid-type objects, such as arch bridges (Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2016, 472 (2190)). Biomedical engineering work on minimal scaffolds for bone replacement awaits funding.
Past research relevant to the automotive and aerospace industries included the convertible roof for the Jaguar XK8, and, at a feasibility level, compressor blades (Engineering Structures 2011, 33, 9, 2612–2620).
