I am a PhD student at the Institute of Cosmology and Gravitation at the University of Portsmouth, supervised by Marco Bruni. My thesis is about how alternative models of dark energy could be a better explanation for the current accelerating expansion of the Universe than the cosmological constant.

I’m particularly interested in models in which the vacuum energy and cold dark matter are coupled, leading to a possible growth of the vacuum through a decay of dark matter. I’ve also recently worked on standard siren and strongly lensed supernovae forecasts, and their applicability as probes of the distance duality relation. You can read my published papers on all these topics here.

I spent my undergraduate years at Aberystwyth University, graduating in July 2017 with a 1st class honours degree in Astrophysics. I was awarded the 2017 Breen Prize for best Master’s dissertation in physics for my dissertation Dynamical Models of Dark Energy and Their Background Cosmological Evolution.

In my spare time, I enjoy playing the violin in various orchestras and recovering in the pub afterwards (sadly only virtually at the moment!). For semi-regular updates about the science I’m doing, plus other topics I find interesting, you can read my blog here.
