About

Dr. Phil Legg is an Associate Professor in Cyber Security and Programme Leader for MSc Cyber Security at the University of the West of England (UWE Bristol), UK. His research interests address many aspects of Cyber Security, including how machine learning, visual analytics, and human-computer interaction are used within cyber security, to improve interpretability and understanding of risk, and to improve robustness and trust of modern security technologies. His research ranges from insider threat detection and cyber situational awareness, through to human-machine teaming for assessing confidence and trust of multiple agents, and active adversarial machine-learning for identifying security vulnerabilities in learning systems. At UWE Bristol, he is an active researcher within the Computer Science Research Centre in the Department of Computer Science and Creative Technologies.

He holds a B.Sc. and Ph.D., both in Computer Science, from Cardiff University. He has also held post-doctoral research and teaching roles at Swansea University and the University of Oxford. He holds a Postgraduate Certificate in Teaching and Learning for Higher Education (Distinction), and is a Fellow of the Higher Education Academy. He is also a professional member of the IEEE and the BCS.
