I’m an Associate Professor of Competition Law and a Fellow and Tutor at Pembroke College, where I teach Contract Law. I’m also part of the Oxford Centre for Competition Law and Policy.
My work explores competition law in the EU, the UK, and beyond. I’m especially interested in using empirical methods - such as building and analysing large datasets, both qualitative and quantitative - to understand how law and policy actually work in practice.
A lot of my research looks at the edges of competition law and how it connects with bigger public policy goals, like sustainability, digital platforms, financial stability, and labour rights. I also study the nuts and bolts of enforcement: how regulators decide which cases to take on, how courts review those decisions, and how competition law plays out in the EU’s multi-level system.
Outside of competition law, I’m fascinated by empirical legal methods, particularly ways of analysing legal texts systematically.
