Research interests
I have been a member of the Quantum Theory Group since its inception in 2013. Initially a Research Associate (first in the CNQO Group at Strathclyde University, before moving to Glasgow University), I became a Research Fellow in 2015 and a Lecturer in 2021. Prior to my life in theoretical quantum optics, I was a Cosmologist (PhD) and Gravitational Wave data analyst (Research Associate) and I am fortunate to have the opportunity to lecture both Astronomy and Physics courses.
