Steve was commissioned in to the British Army serving with 33 EOD Regiment (Royal Engineers) on a Short Service Limited Commission before a full career with the Royal Tank Regiment and Joint CBRN Regiment. This included service in Northern Ireland, Iraq, Falkland Islands, Belize, Canada and Germany. He continues to serve in the reserves as a technical officer.

He left regular military service to join the Foreign and Commonwealth Office spending time in London and the Middle East (he is a fluent arabic speaker). He then worked in Security and Defence consultancy at System Consultant Services Ltd before being head hunted by Thales UK to work on CBRN detection systems. He developed a new type of mobile sensing vehicle (CAS-I) and assessed innovations in detection systems including bees, Deep UV and novel CZT structures for radiation sensing.

Steve spent 2 years working for the leading CBRNE journal, CBRNe World, as deputy editor and head of consulting. He built an explosive detection test house from scratch, co-authored two books on CBRN technologies and had incredible access to CBRNE specialists around the world as he interviewed, visited or helped develop workshops for them. Most recently he resigned as Deputy Editor, taking a position as News editor.

Following developments within his research on the impact of terrorism attacks he was recruited to Intelligence Management Services Ltd where he was Director of Consulting and worked with most of the major players in insurance as well as supporting work on intelligence analysis training and software.

Current activities

Stephen Johnson is the Course Director for the MSc in Forensic Explosive and Explosion Investigation, which explores other hazardous incidents e.g. CBRN and Fire. He actively works with Police, Fire, OGDs and International Organisations on themes of terrorism, CBRNE, intelligence and forensic science. Recently this has included the FCO, ICRC, London Fire Brigade, SO15 and the International Institute of Criminal Investigation.



Steve is lead or co-module manager for the following modules:

·       Hazardous Forensics

·       Forensic Intelligence and Exploitation

·       Forensic Investigation of Explosives and Explosive Devices (FIEED). 

·       Counter IED capability

FIEED is also an elective on the Explosives Ordnance Engineering MSc. 



Research and Consultancy

Steve's research investigates the exploitation of forensic evidence for intelligence purposes and ranges from CBRNE detection through to Open Source Intelligence. He collaborates with Cardiff University, University of Maryland, Georgetown, Imperial College London, King's College London and the University of Sussex amongst others. Recently he supported a successful University of Sussex research bid on CBRN investigations in Syria. His predominant research at the moment is funded by Pool Re (The Government Back Terrorism Re-Insurance Pool), with whom he works closely on the improvement of modelling the impact and forecast of terrorism attacks.


Steve is an internationally recognized expert in the fields of CBRNE, threat modelling and emergency management. He serves on international workshops on chemical detection (ASTM International), CBRN (European Commission Director General - Home Affairs, Joint Research Centre, Interpol, International Committee of the Red Cross, European Defence Agency) and emergency management (Emergency Planning Society's Professional Working Group on CBRN).

Steve consults for public and private sectors in the fields of CBRNE detection, CBRNE Forensics and response, and threat assessment, intelligence and forecasting. He often provides comment on CBRNE and terrorism in the media, e.g., BBC, CNN, Reuters, Washington Post, The Times and Die Welt.
