Biography

I am a Reader (Associate Professor) at Cardiff University and Social Computing research priority area lead in the School of Computer Science & Informatics’ Complex Systems research group. I have developed a reputation for data-driven, innovative, and interdisciplinary research that broadly contributes to the growing field of Data Science, working closely with the Cardiff School of Social Sciences and School of Engineering. I am an applied computer scientist with a principal focus on data and computational methods to improve understanding, operations and decision making outside of academia, while contributing to the academic fields of Social ComputingWeb Science and Cybersecurity.

These three fields are integrated within my research through the  analysis and understanding of Web-enabled human and software behaviour, with a particular interest in emerging and future risks posed to civil society, business (economies) and governments. I achieve this using computational methods such as machine learning and statistical data modelling, and interaction and behaviour mining, opinion mining and sentiment analysis to derive key features of interest.

My research outcomes, which include more than 50 academic articles – stemming from funded research projects worth over £7.2million, are organised and disseminated via two research units:

The Social Data Science Lab, within which I am a director and the computational lead. The Lab’s core funding comes from a £450k ESRC grant and it forms part of the £64m ‘Big Data Network’. Core funding runs between 2017 and 2020, during which time the Lab will host 3 post-doctoral researchers and 9 PhD students, all studying topics related to Risk, Safety & Human/Cybersecurity.

The Airbus Centre of Excellence in Cyber Security Analytics, within which I am the director. The centre works across industry, academia and government to provide a focus for cyber security analytics in the UK. Cyber security is a priority research area at Cardiff University, supported with strategic investment. Since 2012 we have established an interdisciplinary research team of technical and social researchers. Our collaborative projects have received more than £5m in funding from UK Research Councils (EPSRC, ESRC), Welsh Government (Endeavr Wales) and Industry (Airbus).
