Research Interests

 My research focuses on making an optimal use of weak lensing observations to investigate dark energy, dark matter, and the formation of cosmic structures. I am the principal investigator of the OCAPi project (starting in 2026), funded by an ERC Starting Grant, which analyses weak lensing maps at the pixel level. This new technique improves the precision of cosmological parameter constraints and provides a map of the matter distribution in the Universe, effectively making the dark matter visible.

I am also an active member of the Euclid Consortium, where I co-lead the Weak Lensing Science Working Group and contribute to the development of forward models and analyses based on high-order statistics.

My academic path began with a PhD at the Max Planck Institute for Astrophysics, where I developed a method to map the mass distribution of the Universe from quasar spectra (the Lyman-alpha forest) and designed Bayesian tools to address unknown systematics in galaxy clustering surveys. After my PhD, I worked as a postdoctoral researcher at Imperial College London and later as a Beecroft Fellow at the University of Oxford. In December 2025, I moved to the CEA Saclay and joined the Cosmostat group.
