I’m a cosmology postdoc at IPhT CEA Paris-Saclay.

I’m working on the exploitation of gravitational lensing and gravitational waves as probes of dark energy and dark matter. 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 interacting 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.

My career in brief:

I am currently a postdoc at IPhT CEA Paris-Saclay, where I am mainly working with Pierre Fleury on the application of strong lensing observables to cosmology.
From June 2021 to January 2022 I was a postdoc at IFT UAM-CSIC in Madrid, working with Matteo Martinelli and Pierre Fleury.
From October 2017 to February 2021 I was a PhD student at ICG, University of Portsmouth, where I was supervised by Marco Bruni, David Wands and Rob Crittenden. My thesis was entitled Beyond ΛCDM: Current and Future Constraints on Alternative Cosmological Models.
From September 2013 to July 2017 I was an undergraduate at Aberystwyth University. I graduated with a first class MPhys honours degree in Astrophysics and was awarded the 2017 Breen Prize for best Master’s dissertation in physics, for my dissertation entitled Dynamical Models of Dark Energy and Their Background Cosmological Evolution.
