Applied Mathematics and Theoretical Physics

We focus on mathematical modelling and mathematical physics, and investigate everything from neutron stars to superfluids.
String Theory and Holography

The group works on all aspects of fundamental physics - string theory; quantum field theory; applications to gravity, black holes, cosmology, particle physics, condensed matter and quantum information.
