I am a Research Fellow in the Dept. of Computer Science at the University of Oxford. My research interests more generally include computer graphics, rendering, visualization, human visual perception and human-computer interaction. I obtained my BSc (Hons) in Computing Science at the University of East Anglia in 2006, after which I worked a year as an Intrusion Detection System analyst. In October 2007 I began my PhD in Engineering at the University of Warwick where I developed a number of novel computer graphics techniques to appropriately document and reconstruct real-world heritage sites based on 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 understanding how visual analytics can help cyber-security analysts understand cyber-attacks better. In my research projects I have been responsible for creating, implementing and assessing novel visual models. I have also supervised, tutored and lectured undergraduate students in computer graphics at Oxford, and lectured the doctoral students at the Centre for Doctoral Training (CDT) in Cyber Security.
