I am a Postdoc at the Argelander Institut für Astronomie. I work on shear peak statistics, a technique that measures the weak lensing signal around dark matter halos and uses their statistics to constrain the cosmological parameters of our Universe. I also work on characterizing the clustering of faint galaxies in Hubble Space Telescope deep images in order to model its impact on shear measurement in the context of the Euclid space mission.

I obtained a PhD at the Institut d'Astrophysique de Paris in 2015, by analyzing the DAFT/FADA large sample of galaxy clusters at optical wavelengths. In particular, I computed the photometric redshifts of galaxies, and then the cluster galaxy luminosity functions and weak lensing masses.

Here you can find my CV and my list of publications on ADS.
