David completed his undergraduate degree at St Anne’s College, University of Oxford in Materials Science, graduating with a MEng in 2013. His Masters project consisted of fabrication and functionalisation of metallofullerenes for use in quantum computing. In 2013 he moved to the CCMM group in Cambridge to undertake a PhD in the production of collagen films for use in ridge augmentation surgery in collaboration with Geistlich Pharma AG.

Research Interests

My current research is based around adapting the technique of electrophoretic deposition, in which suspended particles form a film through application of an electric field, to work with collagen and other biopolymers to produce multi-layered structures.

Electrophoretic deposition is a widely used technique in the ceramic and paint industries that is beginning to be adapted for use with biomaterials such as hydroxyapatite. It allows for shaped films to be formed quickly with controllable properties such as thickness and density. I am interested in using electrophoretic deposition with biopolymers in order to produce films that can be used for a variety of roles and for rapid production of multi-layered structures. By varying the deposition parameters it is possible to control the growth of each layer individually and produce films that are customised for their roles.
