John graduated with a Master’s degree in Physics from University College London (UCL), before completing an MSc in Composite Materials at Imperial College London. After working for a couple of years, John went on to complete a PhD in Physics at the University of Cambridge. John’s final year Master’s project at UCL was concerned with investigating the magnetic and electrical conductive properties of graphene-intercalated with rare-earth metals at low temperatures. His MSc project was focussed on developing electrically conductive bioceramic composites for prospective bone-tissue repair. His industry funded PhD project spanned subject matter from physics, biochemistry, and food science and technology.

John joined Mewburn Ellis LLP in late 2018 having completed the post-graduate certificate (PGCert) in Intellectual Property Law at Queen Mary (University of London), whilst working as a trainee patent attorney at another London firm. Outside of work, John is a keen footballer, has a passion for cooking, and enjoys travelling, particularly to other European cities and the Mediterranean.
