Postdoctoral Researcher
Bio
I am an Inria postdoctoral researcher in the Quacs group at the LMF. My interests include category theory and its application to problems in physics, particularly quantum theory and models of spacetime.
I completed my DPhil at the University of Oxford. Prior to this I did an MSci in Mathematics at Imperial College London and an MRes in Quantum Technologies at University College London.
