Hannah is a 4th year DPhil student in Social Data Science at the OII and a Research Scientist at the UK AI Security Institute. Her research explores how to align AI systems with the values and preferences of diverse human populations, as well as the threats to human autonomy from the social and psychological capabilities of frontier AI.
Her body of published work spans computational linguistics, computer vision, ethics and sociology, addressing a broad range of issues such as AI safety and security, alignment, bias, fairness, and hate speech from a multidisciplinary perspective. In the past year, her contributions earned a Best Paper Award at NeurIPS 2024 for research on human preference alignment and an Outstanding Paper Award at ACL 2024 for co-authored work on political bias in AI systems.
Hannah holds degrees from the University of Oxford (MSc, Distinction), the University of Cambridge (BA, Double First Class Honours) and Peking University (MA). Alongside academia, she collaborates with industry projects at Google, OpenAI and Meta AI, and previously worked as a Data Scientist in the online safety team at The Alan Turing Institute.
