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.

Before coming to Portsmouth, I did an integrated Master’s degree in Astrophysics at Aberystwyth University in Wales, graduating in 2017 with 1st class honours. I was also awarded the Breen Prize for the best Master’s dissertation in physics. My dissertation, on dynamical models of dark energy, was supervised by Carsten van de Bruck at the University of Sheffield.

Outside of cosmology, I spend my free time playing the violin in various orchestras and recovering in the pub afterwards!
