I’m a cosmologist working on alternative models of dark energy and the exploitation of new observational probes of dark energy and modified gravity such as gravitational waves and strong gravitational lensing. I am also interested in statistical challenges in cosmology, such as the effective use of Markov chain Monte Carlo sampling for parameter inference, and model comparison techniques.
In the past, I’ve worked on models of dark energy 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.
In February 2021, I finished my PhD at the Institute of Cosmology and Gravitation at the University of Portsmouth, where I was supervised by Marco Bruni, David Wands and Rob Crittenden. 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.
