Department of Applied Mathematics and Theoretical Physics

I am interested in theoretical problems in high energy, gravitational and condensed matter physics.

My publications can be found on Inspire, on the arXiv, and on Google Scholar. Videos of some of my talks and lectures can be found on YouTube.

I returned to Cambridge in 2021 to take up the Professorship of Mathematical Physics (1967). I was previously on the faculty in the physics department at Stanford University for 10 years.

I was an undergraduate and graduate student at the University of Cambridge, and then a Junior Research Fellow at Clare College, Cambridge. I then did postdocs at the KITP in Santa Barbara and at Harvard University, before joining the faculty at Stanford.
