- Profile
-
David joined the Department of Chemical and Biological Engineering (CBE) in 2023 as a Lecturer. His research is focused on the development of sensing devices for a wide variety of applications including process, medical, and environmental monitoring challenges. An important component of this work is the development of new technologies that enable the fabrication of these devices. Recently, together with collaborators Jonathan Foster (Chemistry) and Patrick Smith (Mechanical Engineering), David has begun developing Reactive Inkjet Printing (RIJ) for multivariate metal organic framework (MOF) gradients, which is hoped can be utilised for advanced sensors.
David has had a fundamental role in the development of RIJ. In the course of this work he designed, built and developed different Reactive Inkjet Printers including both hardware and software, while he has also developed several modifications to existing printing systems to help promote his research. He remains keen to further expand the development of novel printing technologies.
Further to this David is CTO (Chief Technology Officer) in PHAsT, which promises to become a spin off next year, and is focused on the sustainable production of biocompatible, biodegradable polymers produced via bacterial fermentation. The PHAsT team has recently successfully conducted 100L fermentations with exceptionally high polymer yields at the University of Cambridge facilities, as showcased on their website.
David has also gained work experience in the pharmaceutical industry at Solvay Pharmaceuticals and Abbott Products in Germany, working in the Departments of Medicinal Chemistry, Enzyme Research, and Drug Formulation Development.
Prior to his present position, he was senior postdoctoral research associate (PDRA) to Prof Roy in the Department of Materials Science and Engineering (MSE) at Sheffield University. This post involved the production of natural polymers via bacterial fermentation for biomedical applications as well as the optimisation and development of novel additive manufacturing processes for material processing and tissue scaffold development. In one of the projects multi-material cardiac patches were successfully developed that are currently being tested in vivo.
Having completed undergraduate degrees in Physics with Astrophysics and Cosmology at Lancaster University and Biochemistry and Music at Keele University David went on to study a Masters in Bionanotechnology run jointly between the University of Sheffield and Leeds University. He then joined the Department of Chemical and Biological Engineering for his PhD on catalytic micromotors, under the supervision of Dr Ebbens, which he completed in 2016.
During this time, David was key for the development of RIJ and enzyme powered silk microrockets, which gained considerable media interest and resulted in several high-quality publications and has consequently resulted in him being invited to speak at several national and international conferences.
Thereafter, he worked as a Postdoctoral Research Associate in CBE further developing his work on RIJ of silk materials, which also resulted in the award of two research grants to his PIs, before he moved as senior PDRA to the MSE Department.
