Biography
Dr. George Chalhoub is an Associate Member in the Department of Computer Science at the University of Oxford. He was a Postdoctoral Research Associate (PDRA) on the project Secure Networking by Design, where he worked with the Human-Centered Computing group. He obtained his DPhil (PhD) in Cyber Security through the Oxford CDT in Cyber Security.
Research Interests
George Chalhoub's main research interests the societal impacts of AI, with a focus on the privacy and security risks created by LLMs. His research explores how design practices, legal frameworks, and UX intersect to expose sensitive information, and how law, cybersecurity, and HCI safeguards can reduce these risks. Key areas of interest include:
-
Security and privacy in LLMs and generative AI: investigating prompt disclosure risks, unintended data exposure, and model exploitation, and their societal 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: exploring 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.
