She brings extensive experience from senior roles in the UK government, where she led national strategy on state threats, cyber security and technology policy. Until March 2026, Gemma served as Director for State Threats, Cyber and Technology in the UK Cabinet Office. In this role she led national strategy at the intersection of security, advanced technology and resilience. She helped shape the UK’s £2 billion National Cyber Strategy, developed the UK’s first Counter State Threats Strategy, and co-chaired the National Cyber Advisory Board, bringing together senior leaders across government, industry and civil society to strengthen systemic resilience. She also served as Principal Adviser to the Prime Minister–chaired Science and Technology Committee. During her time in government, Gemma coordinated aspects of the UK’s support to Ukraine following the Russian invasion and led work to manage the UK’s risk exposure to hostile state activity, including malicious cyber and physical attacks. Gemma has extensive experience in strategy, crisis management and national security decision-making. She previously served as Private Secretary to the Prime Minister for Home Affairs and National Security, leading cross-government responses to counter-terrorism incidents, national cyber attacks and major crises, including the Afghanistan evacuation. At the National Cyber Security Centre (NCSC), Gemma established and led national incident response teams and helped build the UK’s cyber incident response capability, overseeing multidisciplinary operations responding to the most significant national cyberattacks. She coordinated real-time operational response and strategic decision-making for ministers, industry leaders and critical infrastructure. Earlier in her career she held senior roles at GCHQ, leading cross-government cyber defence initiatives and contributing to the development of the UK’s first National Offensive Cyber Strategy. Her work focuses on resilience as a strategic pillar of national power, integrating behavioural insight, adaptive governance and international cooperation. She has advanced resilience frameworks with Five Eyes partners, the EU and the United States, and contributes to debates on democratic resilience, responsible AI governance and the security implications of emerging technologies.
