I hold an MSc in Cyber Security and an undergraduate degree in Cyber Security Science. Before starting the CDT, I worked as a Security Analyst, which gave me a practical view of how security decisions play out inside a real organisation.

My research interests sit where machine learning and security meet. I am particularly interested in explainable AI, privacy-preserving federated learning, and the security of large language models, including how they can be attacked and how we can make their behaviour easier to trust. More recently, I have become curious about usable security, and whether security practices can be designed so that people follow them naturally rather than working around them.
