Charles worked as a graduate engineer and high-school physics teacher prior to undertaking a PhD at University of Southampton. During his PhD, he was a member of the tribology research group (nCATS), where he investigated the dynamic loading caused by high-speed water droplet impingement on aeroengine fan blades. Charles now enjoys applying the skills he developed during his PhD, as well as learning new ones, as a Research Fellow on the APRICOT project (www.apricot-project.eu). This international, multi-million Euro project, seeks to develop a radically new type of implant for the treatment of small joint arthritis – minimally invasive, bone conserving and suitable for patients of all ages. Charles has led the modelling of the implant in vivo and use of statistical shape analysis to characterise the variability in patient joint geometry.
