About
My research focuses on human-centred cybersecurity: how end users and developers make security decisions under real-world constraints such as limited attention, incomplete knowledge, time pressure, and competing goals. I examine how people make security decisions in context, evaluate whether current systems support those decisions, and design interfaces and tools that make security information visible, understandable, and actionable.
I also teach a postgraduate course on Usable Security and Privacy, where students engage with foundational research, discuss current issues, and design their own usable-security studies.
