Dr Theo Tryfonas


I am a Reader in Smart Cities with a background in cybersecurity, systems engineering and software development. I work with the Cryptography Group and the Systems Centre and I am involved in doctoral supervision with the engineering doctorate (EngD) in Systems, as well as with teaching across our Computer Science MSc and the undergraduate programmes of Engineering Design and Civil Engineering. I am also the Director of Postgraduate Research Studies of Queen's School of Engineering.

In the past I worked as a programmer (Ulysses Systems), consultant and auditor (Ernst & Young) and have kept close ties with industry after becoming an academic, providing on occasion expert witness advice, continuing professional development courses etc. My work has been focused on a diverse range of sectors including transportation, utilities, healthcare and government. I have worked in particular on aspects of marine safety and port security, public transport resilience, protection of UAVs, telecom revenue and system assurance, as well as contributed to investigations of computer-assisted crime.

I graduated with a BSc in Computer Science from the University of Crete in Greece. I then moved to Athens to complete my postgraduate studies, first at master's (MSc Information Systems) and then at doctoral level (PhD Informatics). My PhD was sponsored by Ernst & Young, one of the "Big Four" global assurance and advisory firms. I'm a Felow of the Royal Society of Arts and a Chartered Professional Member of the Chartered Institute for IT (MBCS CITP). I'm also a Certified Information Systems Auditor (CISA) and an academic advocate member of ISACA.

In my spare time I enjoy spending quality time with my daughter Chrissa-Sophia, my little boy Gabriel and my wife Catherine. I also like sport (a lot), mainly rugby but also many others such as cricket, american football and MMA. And for some random reason I am fascinated by church architectures.
