Astronomer · Computational Engineer

I build open-source software and pipelines for large-scale astronomical experiments, at the intersection of signal processing, machine learning, and observational cosmology.
I work for the CNRS Nucléaire & Particules and am currently based at AstroParticule & Cosmologie (APC) laboratory in Paris, where I lead the IT department Computing and data engineering group.

In 2024–2025 I spent a year on-site in Chile commissioning the filter exchange system of the LSST camera (see photos below)
