About Prof John Brammer

Prior to joining Chester in early 2016, John worked at Aston University as a Lecturer then a Senior Lecturer in Chemical Engineering. He started at Aston in 1997 as a Research Assistant, and completed a PhD in 2001 in the production of energy from biomass. John obtained a Lectureship in the Chemical Engineering and Applied Chemistry subject group in 2002, and since then has developed his teaching to include heat and mass transfer, process simulation, process economics and particle technology. He is also active in research in the field of energy systems. He obtained a Senior Lectureship in 2013.

Before entering academia, John worked extensively in industry, with both Rolls-Royce plc on aero gas turbine combustion, and with PowerGen plc primarily on stationary boilers. His employment record is as follows

  • 2016 - present: Professor in Chemical Engineering, University of Chester
  • 2013 - 2015: Senior Lecturer, Chemical Engineering and Applied Chemistry, Aston University
  • 2002 - 2013: Lecturer, Chemical Engineering and Applied Chemistry, Aston University
  • 1997 - 2002: Research Assistant, Bioenergy Research Group, Aston University.
  • 1990 - 1995: Group Leader, Combustion Section, Power Technology, PowerGen plc., Nottingham
  • 1983 - 1990: Technologist, Combustion Department, Engineering Division, Rolls-Royce plc, Derby


John has taught the following subjects to students on Chemical Engineering and Applied Chemistry undergraduate programmes:

  • Heat Transfer to Level 4, 5 and 6 students
  • Process Simulation to Level 5 students
  • Chemical Engineering Laboratory to Level 5 students
  • Process Economics to Level 6 students
  • Particle Tecnology to Level 6 students
  • Mass Transfer to Level 5 students
  • Design Project to Level 6 students
  • Meng Research Project to Level 7 students

PhD Supervision

Completed: 9 students in various topics. Available to supervise new suitable applicants in the field of energy systems analysis, and design analysis and modelling of energy system components.


John's research interests are in the field of energy production systems, in particular bio-energy systems. He specialises in overall system modelling and analysis, and also in computational fluid dynamics analysis of individual plant components. He also carries out experimental research in gasification and pyrolysis systems.
