Theoretical High Energy Particle Physics Group



  • 2021-present: Stephen Hawking Fellow, University of Cambridge
  • 2018-2021: Research Fellow (Emmanuel College), University of Cambridge


Scott is a member of the Department of Applied Mathematics and Theoretical Physics High Energy Physics research group.

His current research interests include various aspects of quantum field theory, in particular effective field theories and their application to problems in gravity and cosmology.
