I am a post-doctoral researcher in the Mathematical Physics Group working under the supervision of Dr Eva-Maria Graefe. My previous research has been in the areas of open topological systems and topological lasers. Additionally, my current research interests include open systems, classical and quantum chaos and random matrix theory (RMT). My current research involves the real Ginibre ensemble and it's links to parity-time (PT) symmetric systems. 

Previous Affiliation & Useful Links

My PhD was undertaken in Lancaster University under the supervision of Professor Henning Schomerus.
