My research concerns the numerical modelling of wood and timber components. One part concerns algorithms to create high-fidelity models based on X-ray computed tomography (CT) scans of timber, and the other part concerns models to understand disproportionate collapse and the development of alternative load paths in multi-storey timber buildings.
