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 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.
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.

March 2018 - I have been appointed as programme leader for the new MSc Cyber Security at UWE Bristol. We are currently looking to recruit talented and motivated students who are interested to gain skills for dealing with modern threats in cyber space, for our first intake of September 2018. Please visit the course page for futher detail and information on how to apply.
February 2018 - Research by our team in the AI group (Smith, Legg, Matovic) and the UWE psychology department (Kinsey) has been accepted for journal publication in ACM Transactions on Interactive Intelligent Systems (TiiS). The paper, entitled "Predicting User's Confidence during Visual Decision Making" will be included in an upcoming special issue on the topic of Human-Centered Machine Learning.
January 2018 - Our team (Legg, Smith, Preen) have been awarded funding by the Defence Science and Technology Laboratory (DSTL) in order to conduct research on human-machine collaboration. The Defence and Security Accelerator (DASA) project, entitled "HASTE: Human-centric Active-learning for decision Support in Threat Exploration" will commence from February 2018.
November 2017 - I served on the National Cyber Security Centre (part of GCHQ) assessment panel for the Academic Centres of Excellence in Cyber Security Research Doctoral Studentships Programme.
October 2017 - Professor Min Chen (University of Oxford) presents our recent work at IEEE VIS in Phoenix, Arizona USA, on how communication theory can inform design separability in glyph visualisation, with a use case of visualising collaborative employee activity across complex shared file servers.
September 2017 - Emmanuel Smith presents our recent work on time-series event prediction using Long Short-Term Memory networks at the UK Workshop on Computational Intelligence in Cardiff.
August 2017 - I was invited to Adarga to give a talk on "Human-Machine Collaboration in Active Machine Learning".
July 2017 - Alexander Downing (1st Year Undergraduate at UWE Bristol) joins the AI research group on a 10-week Summer Internship scheme, working with Dr. Legg to develop visual analytic tools for interacting with machine learning processes.
June 2017 - Dr Arnau Erola (University of Oxford) presents our recent work for the DSTL-funded RicherPicture project, on context-aware data analytics for improving organisational cyber security at the International Conference of Cyber Situational Awareness, Data Analytics and Assessment (CyberSA) in London.
May 2017 - I was interviewed by the Bristol Post to advise on how to stay safe online, following the recent WannaCry global cyber attack.
January 2017 - My book chapter on developing human-machine decision support systems for insider threat detection has been accepted for the upcoming Springer edited book, "Data Analytics and Decision Support in Cybersecurity".
ResearchMany of the research projects I am involved with sit at the intersection of data visualisation, visual analytics, machine learning, and cyber security. I am keen to establish new multi-disciplinary collaborations so that my expertise can provide practical real-world solutions for others. I can also offer business consultancy to help transform research ideas into practical development of software tools.
