James is the Head of Cyber Research at RUSI. His research interests include cyber security, the spread of terrorism and violent extremism in cyberspace, online disinformation campaigns, and the role of emerging technology in defence and security.

RUSI’s cyber security research agenda focuses on five thematic areas: the cyber threat landscape; improving defence and resilience; the role of legislation and regulation; online education, awareness and behaviour; and the UK cyber ecosystem.

He worked closely with UK government, private sector and international partners to identify and make sense of global cyber threats and trends, to provide security guidance to citizens and organisations, and authored strategic reports relating to specific malware strains, banking trojans, ransomware, and denial-of-service attacks. 

James holds an MSc in Security Studies from University College London (UCL), where his dissertation explored the motivations behind suicide terrorism. He also holds a degree in Spanish and Portuguese from The University of Nottingham.
