My name is Florent Leclercq. I am a Research Fellow at the Imperial Centre for Inference and Cosmology. I work in the fields of theoretical and observational cosmology, focusing in particular on the analysis of galaxy survey data.

My current research interests are related to the study of the cosmological large-scale structure using statistical data analysis tools. I am particularly interested in the initial conditions from which the large-scale structure originates, its formation history and the description of the cosmic web.
