Professor Paul Smith’s research is concerned with the cyber security and resilience of critical networked systems, with a focus on digitalised critical infrastructures such as those found in the nuclear sector. He is interested in understanding the risks and benefits associated with digital innovation for critical infrastructures and investigating approaches to ensuring their resilience when subject to disruptions, such as cyber-attacks. He has published extensively on these issues and has taken a leading role in numerous national and international research projects. Paul is enthusiastic about knowledge exchange and, for example, collaborates extensively with the International Atomic Energy Agency (IAEA), supporting their computer security programme.
