John received his PhD degree from the University of Cambridge in 2005 for research in the field of fouling and cleaning of process surfaces. After his PhD, he was awarded the prestigious five-year Royal Academy of Engineering Research Fellowship to work on developing surface sensors for monitoring fouling and cleaning of membranes and heated surfaces, also based at University of Cambridge. After this, he took up his lectureship post at the Department of Chemical Engineering at University of Bath.

John has held a number of significant leadership and management roles in the Department, including:

  • Admissions Tutor (2013-2016)
  • Director of Teaching (2016-2020)
  • Deputy Head of Department (2020-2022)
