I am a cosmologist specialising in the analysis of large scale structures in the Univese. My aim is to understand the overall makeup of the Cosmos and in particular, the dark matter distribution, and the nature of dark energy. I am probably best known for my recent weak gravitational lensing analysis of the Kilo Degree Survey (KiDS-1000), which includes images for 30 million galaxies! We combined this weak lensing data with other probes of the large scale structures and set tight constraints on cosmological parameters, especially, the structure growth parameter, S8. I am currently a lecturer at the University of Hull.
