John Proctor received his Ph.D. from the University of Manchester in 2008. Since then, his research has been devoted to the field of high-pressure physics. Primarily using the diamond anvil high-pressure cell, he has focused on nanotubes and graphene, superhard materials, hydrides, and, in recent years, supercritical fluids. He is now a senior lecturer in Physics and head of the Materials and Physics research group at the University of Salford. He recently published his first textbook, An Introduction to Graphene and Carbon Nanotubes, and he has written for Physics World.
