His interests are now mainly in research. He sees Structural Mechanics as a wide and inter-disciplinary field that provides many challenging, interesting and unexpected problems. For example, progress made in grappling with new structural phenomena in civil, mechanical and offshore engineering leads to more rational design methods in these fields; while at the other end of the spectrum, and on a much smaller scale, there is much scope for the elucidation of subtle phenomena in microscopic and sub-microscopic biological structures. And there are regions in-between - such as deployable structures - where cross-fertilisation of ideas can lead to new structural concepts that are of great interest to the aerospace industry.
