About

I am a cosmologist developing simulations, statistical methods and observational tests to understand the physics driving cosmic acceleration. My research focuses on modified gravity and dynamical dark energy, their signatures in the nonlinear large-scale structure of the Universe, and how these signatures can be tested with surveys including DESI, Euclid and Rubin LSST.

I am currently a Research Fellow at the Institute of Cosmology and Gravitation at the University of Portsmouth, working with Prof. Tessa Baker.

Research

Gravity and cosmic acceleration

I investigate whether modified gravity can provide a physical explanation for dynamical dark energy and other departures from the standard cosmological model. My work develops viable theoretical models and identifies observable signatures that distinguish them from conventional dark-energy scenarios.

Simulating nonlinear structure formation

I develop fast N-body methods for predicting how modified gravity and dark energy affect the nonlinear growth of cosmic structure. This includes my work as a lead developer on Hi-COLA, which connects theories beyond General Relativity to predictions for large-scale structure.

The cosmic web as a cosmological probe

I develop statistical methods that extract information from the geometry and connectivity of the cosmic web. These include minimum-spanning-tree statistics, field-level methods and tools for identifying structures such as voids, walls, filaments and clusters.

About me

I was born in Mauritius and moved to the United Kingdom when I was five. Outside research, I enjoy reading, drawing and painting, building miniature models, playing video games, and following football and Formula 1.
