Summary/Biography:

I studied for my PhD in Mechanical Engineering at the University of Leicester from 2010-2013. This research involved the development of mathematical models for the degradation of bioresorbable polymers that are used in the human body for medical applications. A new atomic-scale finite element method enabled new understanding into how polymer chain scissions affects mechanical properties.

After my PhD I undertook additive manufacturing research at the University of Nottingham with a particular focus on medical applications. The polymers that I studied during my PhD were used to fabricate tissue engineering scaffolds. We created software to control bioprinters in a novel way, enabling advanced structures to be produced beyond the capabilities of commercial software. To support the prediction of the mechanical properties of these new structures, we also developed a 3D voxel modelling routine (called the VOLCO model) to simulate the material extrusion additive manufacturing process.
