I am a cosmologist working at University College London. To answer questions about the origin and evolution of the Universe, I develop specialised machine learning and statistical techniques. Recently, I led the team that created the Dark Energy Survey's dark matter map. I now also work on the Dark Energy Spectroscopic Instrument (DESI) and the European Space Agency's Euclid mission (launched 1st July 2023).

After completing my MSci in Theoretical Physics at Imperial College London, I completed my PhD at University College London supervised by Prof. Ofer Lahav, before going on to be a Research Fellow at the École Normale Supérieure, Paris.
