Final-year PhD Researcher · Computer Science

University College London · Centre for AI

I work at the intersection of technical AI research and its governance and societal implications. My current research examines reasoning and rationality in large language models, including the downstream consequences of deviations from expected behaviour. I combine a background in computer science, mathematics, and international relations with experience producing research for academic, government, and industry audiences.
