Jamie Crispin PhD

Dr Jamie Crispin is a Postdoctoral Research Assistant at the University of Oxford currently working on the PICASO joint industry project with Ørsted. This involves the interpretation of large-scale field test data on monopile foundations and the development of new design methods for the foundations of offshore wind turbines under cyclic loading.

Prior to joining Oxford, Dr Crispin completed his PhD at the University of Bristol on the static and dynamic analysis of piles and pile groups. In this work he developed original analytical solutions as well as contributing to the DINGO project, which involved collecting and analysing a database of over 500 onshore pile tests.

Dr Crispin works on the development of analytical, theoretical, and numerical solutions to soil-structure interaction problems related to static, dynamic, and cyclic loading. This research is focussed on predicting the deformations of monopiles and pile groups, as well as retaining walls, surface foundations and tunnel-foundation interaction problems.
