His research interests address many aspects of Cyber Security, including how visual analytics and machine learning can improve intepretability and understanding of risk, and improve robustness of modern security technologies. His research ranges from insider threat detection and cyber situational awareness, through to human-machine teaming to understanding confidence and trust of multiple agents, and active learning from limited data samples in security appliances. Other related interest areas include Vision, Graphics, Visualisation, and Human-Computer Interaction. At UWE Bristol, he is an active researcher within the Computer Science Research Centre in the Department of Computer Science and Creative Technologies.
