Mathieu Puech

Welcome  to my (forever-in-construction) web-page!

Astrophysicist / Astronomer

Since 2022I am an «Astronome» (Equivalent to a professorship position in astronomy) at GEPI, one of the Paris Observatory labs. I am working on galaxy formation and evolution and share my time between astronomical research, instrument development, and teaching.

You can (try to) find me at the Meudon Observatory, «Grands Communs» building, Office #163 (2nd floor, Paris aisle).

Check out whether I’ll go to your meeting there.
