Dr. George Chalhoub

I am a Lecturer (Assistant Professor) in Human–Computer Interaction at the UCL Interaction Centre (UCLIC), a Faculty Associate at the Berkman Klein Center for Internet & Society at Harvard Law School, and an Associate Member of the Department of Computer Science at the University of Oxford.

I am interested in understanding and improving the societal impacts of AI, with a particular focus on the privacy and security risks posed by LLMs. My work explores how design practices, legal frameworks, and user experience intersect to expose sensitive information, and how safeguards across law, cybersecurity, and HCI can reduce these risks.

My main research interests include:

• Security and privacy in LLMs and generative AI: investigating prompt disclosure risks, unintended data exposure, and model exploitation, and their consequences in domains such as healthcare, law, and journalism.
• User experience of AI security: studying how people interact with AI systems, how misconceptions create new vulnerabilities, and how interfaces can be redesigned to protect sensitive data.
• AI governance and legal frameworks: analysing how regulation, platform policy, and institutional practices affect privacy, accountability, and democratic oversight.
• Risks to vulnerable groups: examining how marginalized communities, online creators, and data workers are disproportionately exposed to AI-driven harms.
• Human-centred safeguards: developing technical, legal, and UX-based interventions that mitigate misuse and strengthen resilience in high-stakes contexts.
