Staff profile

I am a Professor in the Department of Mathematical Sciences at Durham University. I completed an MPhys and DPhil in Theoretical Physics at the University of Oxford, followed by postdoctoral positions at The Institute for Advanced Study in Princeton, Perimeter Institute for Theoretical Physics, and the University of Oxford.

My research investigates mathematical structures in quantum field theory, with a particular focus on supersymmetry and generalised symmetries. I was recently awarded an ERC Consolidator grant to lead a research team developing the mathematical foundations of generalised symmetries, with the goal of uncovering new principles and deepening our understanding of quantum systems. I am also a member of the Simons Collaboration on Global Categorical Symmetries and previously held an EPSRC Fellowship to explore aspects of supersymmetric quantum field theory.

I currently serve as Deputy Director of Postgraduate Research and PhD Admissions Officer for the Mathematical and Theoretical Physics group. For information about PhD opportunities in the group, please click here.

My publication record is available on INSPIRE.
