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. I have been a member of the Aquila Consortium since it was created, in 2016.
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.

I have written a post on the Aquila Consortium's website regarding my last two papers on BOLFI and SELFI. It is available here: Algorithms for likelihood-free cosmological data analysis.
