Dr Cyril Closset
Status
Visiting Professor, Research Fellow, Lecturer
I am a Royal Society University Research Fellow in mathematical physics. The main focus of my research is on mathematical and "formal" aspects of Quantum Field Theory (QFT) in the presence of supersymmetry. The underlying "big question" is: How do we use supersymmetry to learn more about QFT at strong coupling? Along the way, there are quite a few beautiful mathematical structures to be uncovered. Many of the problems that I work on arise in string theory, or have deep relations to it.
