Dr John Ewer PhD, MSc, BSc.

Associate Professor in Applied Fire Safety Engineering

Dr John Ewer (he/him) is the Fire Research Team Leader for fire modelling research and the SMARTFIRE commercial software development in the Fire Safety Engineering Group (FSEG).

Dr Ewer is currently working on a number of fire safety and general safety related projects, including:

  • September 2022-ongoing: Healthy Sailing EU Horizon Project: developing a scientific evidence base, modelling tools and guidance in support of the Prevention, Mitigation, and Management (PMM) of disease outbreaks on passenger vessels.
  • 2018-ongoing: Leading a ‘buildingSMART’ project to develop standards focusing on the incorporation of FSE into BIM standards in support of preserving the ‘Golden Thread of Information’.
  • 2018-ongoing: The development of an Integrated Ship Survivability Assessment Capability (ISSAC) for the Australian DSTG (Defence Science & Technology Group),
  • 2020-ongoing: Research and development of a Virtual Training Environment (VTE) for aircraft crew training for emergency evacuation in survivable crashes.

2020-ongoing: During the Covid pandemic, Dr Ewer was awarded University of Greenwich Proof of Concept Innovation funding, and led the research team to develop modelling capabilities for indoor aerosol dispersal and infection risk modelling. This project included features such as moving sources, targets, and wake flows – based on scalar-gas and droplet dispersion using a localised ‘Wells-Riley’ method to determine infection risk.

Current Doctoral Supervisions:

  • Dr Ewer is currently supervising two VC Scholarship PhD researchers in their investigation of the fire dynamics in baled waste; and fire safety issues of high-rise buildings.

He has successfully supervised three PhD researchers in:

  • A Knowledge Based System supported control of fire modelling simulations;
  • Research into geometry optimisation of building evacuation;
  • Developing a data sharing strategy for Building Information Modelling (BIM) and Fire Safety Engineering (FSE).

Key Research, Enterprise, and Academic Activities:

  • 2012-ongoing: Dr Ewer is a co-ordinator and lecturer on the annual ‘Principles and Practice of Fire Modelling’ CPD (continuing Professional Development) short course, held online and face-to-face at the University of Greenwich.
  • 2015-ongoing: Dr Ewer has developed a strand of consultative work to review third party fire strategy submissions to Building Control services.
  • 2021-ongoing: Dr Ewer leads the Software Engineering BEng.  module COMP1714: ‘Software Engineering Management’ and tutors as well as supervises undergraduate and postgraduate project students.
  • 2008, 2014, 2021: Dr Ewer was included in three highly successful FSEG Research Excellence Framework (REF) submissions with significant contributions to the fire modelling related impact studies.

Awards and Achievements:

  • 2021: Dr Ewer attained a Gold/HEA (Higher Education Academy) Fellowship.
  • His research and publications have received numerous awards.
