Simon is an Assistant Professor in the TPM Cybersecurity group, specialising in human-centred security - usability and perceptions of security-related technologies, security behaviour change, security economics, and decision-making in security management. Before joining TU Delft, Simon was a Senior Research Fellow at UCL, 2012-2020. Simon completed his PhD at Newcastle University in 2007, and was a Research Associate through to 2011 and member of the Innovation Team at HP ESS until mid-2012.

Simon’s current research examines how stakeholders in security and privacy can identify and limit unintended harms to users in technology, support, and policy decision-making. Research also continues into the use of both security and behavioural economics to address gaps in user support within organisational settings, and usability challenges of shared consumer IoT environments.
