Tommy van Steen

Leiden University is inviting applications for two fully funded PhD positions (4 years) and one fully funded postdoctoral position (2.5 years) in the field of organisational and behavioural cybersecurity. These positions are part of an NWO-funded project focused on understanding what works well in supporting cybersecurity within organisations, teams, and individuals. The research aims to generate actionable insights that help organisations improve their cybersecurity practices by learning from successful strategies, rather than only from past mistakes. The successful candidates will be based at the Institute of Security and Global Affairs, Faculty of Governance and Global Affairs, Leiden University, located in The Hague, Netherlands. The project is supervised by Associate Professor Tommy van Steen, with additional involvement from Bibi van den Berg, Sanneke Kuipers, Jeroen Wolbers, and Cristina Del Real. The research group is internationally recognized for its work at the intersection of cybersecurity, organisational behaviour, and governance. Applicants do not need prior knowledge of behavioural or organisational cybersecurity, but should demonstrate eagerness to learn and a relevant academic background suitable for PhD or postdoctoral research. The positions are fully funded, though specific stipend amounts and tuition coverage details are not provided. The application deadline is one week from the posting date, approximately December 28, 2025. To apply, candidates should visit the English Career page of Leiden University and search for the relevant vacancies under the Faculty of Governance and Global Affairs. For further information or questions, applicants are encouraged to contact Associate Professor Tommy van Steen. This opportunity is ideal for those interested in cybersecurity, organisational behaviour, and interdisciplinary research in a leading European institution.
