About Graham Leigh

My research concerns the interface of three concepts central to logic: proof, truth and computation. Much of my work examines links between these concepts, such as axiomatic theories of truth, infinitary (and non-wellfounded) notions of proof, and computational content of classical logic. I have published articles on ordinal analysis (proof theory), philosophy of mathematics, intuitionism, and temporal logics, and a monograph The Road to Paradox: A Guide to Syntax, Truth and Modality with Volker Halbach (October 2024).

I joined the logic group as Researcher in 2016 with a Wallenberg Academy Fellowship and was appointed Docent in 2018, Senior Lecturer in 2022 and full professor in Autumn 2024. I am editor of The Review of Symbolic Logic.

For information about our research seminar in logic and activities of our group see our group webpage (external).

The Road to Paradox: A Guide to Syntax, Truth and Modality

Co-authored with Volker Halbach (New College, Oxford), The Road to Paradox (CUP) provides a clear and direct introduction to the theory of paradoxes and the Gödel incompleteness theorems. It offers new analyses of the ideas of self-reference, circularity, and the semantic paradoxes, and helps readers to see both how paradoxes arise and what their common features are. The book can be ordered directly from the publisher.
