My research interests include (alphabetically listed) Computer Graphics, Cyber Security, Human Factors, Human Visual Perception, Rendering, Virtual Archaeology and Visualization. I obtained my BSc (Hons) in Computing Science at the University of East Anglia in 2006. After a year working as an Intrusion Detection System (IDS) analyst, I began a PhD in Engineering at the University of Warwick in October 2007 where I developed a number of novel computer graphics techniques to document and reconstruct real-world heritage sites based on empirical evidence available today. I successfully defended my PhD in January 2012, and have since December 2011 worked at Oxford. In more recent years spent I have spent my research efforts on cybersecurity analytics through visualization, covering topics such as threat modelling, situational awareness, risk propagation, decision support, privacy as well as cyber threat intelligence sharing. In my research projects I have been responsible for creating, implementing and assessing novel visualization techniques. Teaching wise I tutor and lecture the Computer Graphics course. I also lecture doctoral students for the Centre for Doctoral Training (CDT) in Cyber Security in topics such as situational awareness, intrusion detection and security architecture. Finally, I also supervise undergraduate, MSc and doctoral projects. I am also a Research Common Room Member at Kellogg College.
