ISMOR is an annual international symposium sponsored by the UK Ministry of Defence which offers a unique opportunity to spend quality time exploring the application of analysis to practical issues of defence and security with a wide range of colleagues from across the world.

Following the global Coronavirus crisis ISMOR returned in July 2022 for its 39th edition as a residential event, with selected elements available to remote attendees. For the 40th edition ISMOR will return to being a fully residential event however the committee is considering the opportunity to broadcast the conference sessions.

ISMOR 40 will be held at Royal Holloway University from the 18-20 July 2023, with the intention that participants arrive on the afternoon/evening of 17 July, for a prompt start the following morning. ISMOR provides the opportunity to learn about the latest defence analysis methods and techniques through:

  • Presentations from experienced practitioners.
  • Formal and informal discussion with defence professionals and leading experts from across the globe.
  • Interactive sessions such as workshops and seminars.

As well as inspiring experienced practitioners with new approaches and providing informal testing of ideas, ISMOR offers an excellent development opportunity for early career analysts.

As this is a notable anniversary the committee is also seeking to organise a special event, in addition to the usual special keynote speaker and symposium dinner, to make this a truly memorable ISMOR.

We will shortly announce more details regarding the format, charges, and themes for ISMOR 40, together with a call for abstracts and registration.

Meanwhile, please keep the week of 17-20 July 2023 free, and start thinking about what you want to present!

We look forward to welcoming you to ISMOR 40.
