Summary

 

Summary

I am a Royal Society University Research Fellow and proleptic Senior Lecturer in the Mathematical Physics Group. I am working on the development of a semiclassical framework for non-Hermitian quantum theories.

My research background is in theoretical quantum dynamics in the context of atomic physics, and in particular the description of ultracold atoms and Bose-Einstein condensates. In this context I have been working on non-Hermitian and PT-symmetric quantum theories, semiclassical methods and quantum chaos.
