“I studied Physics at St Andrews University and Applied Optics at Imperial College. I began my career with Ferranti in Edinburgh as an optical engineer, working first on laser system projects, led the optical design team for the UK’s first airborne multi-spectral electro-optical pod, and played a key role in developing the company’s infra-red countermeasures business. I shifted to Thales Optronics in 1993, serving as Chief Systems Engineer and Chief Engineer. Seconded to Thales UK Corporate in 2003-04 as Director Prime Contract Support, I made contributions to programmes including Soldier Systems, the Future Carrier, and UAV / C2 systems. From 2005-08 I was seconded to UK MOD as Head of Integration, responsible for managing system-of-systems interoperability. I returned to Thales to become Chief Systems Architect for the Thales Land and Joint Systems Division in the UK, and then Thales UK Systems Engineering Director, with an overview of a very wide range of complex system developments including transport sector, and was appointed a Thales Fellow. 

I’ve been awarded eight patents and made a number of notable contributions to the Systems Engineering literature, including “Design principles for ultra large scale systems” (Best Paper Award at the INCOSE International Symposium, Chicago 2010), contributions to the BKCASE Systems Engineering Body of Knowledge, and my recent book “Architecting Systems – concepts principles and practice” (College Publications 2014). I’ve been appointed to Visiting Professorships at the Universities of Bristol and Strathclyde.

I’m a Chartered Engineer, Fellow of the Institute of Physics, Fellow of the International Council on Systems Engineering, past president of the INCOSE UK Chapter, certified Expert Systems Engineering Professional (ESEP), and have recently been elected a Full Member of the Omega Alpha Association.”
