In broad terms, my main research interests are in applying structural and logical methods from mathematics and theoretical computer science to physics, and beyond. My present focus is largely on enhancing our understanding of the foundations of quantum theory, and on harnessing this for the development of quantum technologies.

Much of my research focuses on the key non-classical aspects of quantum theory, such as non-locality and contextuality. From a foundational perspective, these lie at the root of many of the conceptual issues arising from quantum theory, while from a practical perspective they also underpin the utilisable advantages of quantum systems and the huge potential of quantum technologies.


I am currently a Marie Skłodowska-Curie Individual Fellow based at Sorbonne University, Paris. There I lead a research project on Resource-Sensitive Quantum Computing (ResQu) as a member of the Quantum Information team in the computer science laboratory LIP6.

I have previously held fellowships and postdoctoral research positions at the University of Oxford, Paris Diderot University and the University of Edinburgh. From January to August 2017 I was a postdoctoral researcher at the School of Informatics, Edinburgh, in the group of Professor Elham Kashefi. In 2016 I held a postdoctoral fellowship from the Fondation Sciences Mathématiques de Paris, for my project Contextual Semantics for Quantum Theory, working with Christine Tasson at IRIF, Paris Diderot University. Prior to that I held postdoctoral positions at Oxford, working first on the Oxford Martin School‘s programme for Bio-inspired Quantum Technologies and later for the Networked Quantum Information Technologies hub of the UK’s National Quantum Technologies programme. I was based primarily in the Quantum Group at the Department of Computer Science, while also being associated with the QuNaT Group at the Department of Materials. During this time, I was an Oxford Martin Fellow and a Junior Research Fellow of Wolfson College (2013-16), where I was organiser of the meetings of the Quantum Foundations Research Cluster.

I completed my DPhil [doctorate] in Computer Science at the University of Oxford in 2013 with Samson Abramsky and Bob Coecke with a thesis entitled The Mathematical Structure of Non-locality and Contextuality. My examiners were Lucien Hardy and Jamie Vicary. I also hold an MASt in Applied Mathematics and Theoretical Physics (Part III Mathematics) from the University of Cambridge, an MSc in Physics (numerical relativity), supervised by Niall Ó Murchadha, and a BSc (joint honours) in Physics & Mathematics, both from University College Cork. I was awarded a National University of Ireland Travelling Studentship for my doctoral studies in 2010.
