Dr Sargeant's research explores the critical intersection of law and artificial intelligence, seeking to build robust frameworks for responsible AI governance. She is principally concerned with two key questions: how should our laws adapt to ensure that AI is designed and deployed ethically, and how can AI itself be leveraged to improve legal research and access to justice? Her doctoral thesis examined these questions within the context of consumer finance. It offered recommendations for regulation by analysing the corporate incentives for using new technology alongside the normative implications for consumers. As a Research Fellow at St John's, she is expanding this work into a new postdoctoral project. This project widens the scope to compare additional jurisdictions and different high-stakes applications of AI, with a particular focus on tackling the problem of algorithmic discrimination. Additionally, she explores AI's role in legal research and access to justice, including projects evaluating biases in legal datasets and the use of AI-assisted judicial decision-making.
