John was a senior lecturer in chemistry education at Nottingham Trent University.
John worked as a research chemist before deciding to take a leap of faith and change career. He retrained as a teacher and spent ten years in three different secondary schools, as a chemistry teacher and head of department. He was an examiner and advisor to a UK exam board, and contributed to the development of the revised A-level chemistry specification.
In September 2012 John moved to Nottingham Trent University as a senior lecturer in chemistry education and PGCE/PGDE course leader. He was a member of the Education in Chemistry editorial board and a chair of the RSC’s chemistry subject knowledge enhancement working group.
