Background

I am a Lecturer and STFC Ernest Rutherford Fellow in the Cosmology & Quantum Gravity Group.

Before moving to Newcastle, I held research positions at Durham University, Imperial College London, the Perimeter Institute for Theoretical Physics, and the University of Amsterdam. I completed my PhD at DAMTP, Cambridge.

My research interests include:

- Holographic gauge/gravity dualities
- Conformal field theory
- Early universe cosmology
- General relativity

My publications can be found on INSPIRE or Google Scholar.

Teaching

- MAS8814 Advanced Concepts in Applied Mathematics: Quantum Field Theory (2020/21, 2019/20)
- Cosmology II, MSc in Particles, Strings & Cosmology, Durham University (2018)
