Guillaume Lauga
I am preparing a PhD at École Normale Supérieure de Lyon since November 2021 under the supervision of
Paulo Goncalves,
Elisa Riccietti and
Nelly Pustelnik.
I am a member of the Inria OCKHAM team
of the LIP laboratory and my PhD is funded by Inria.
My work focuses on multilevel optimization methods for proximal based algorithms.
