Since September 2019, I am an Associate Professor at Université Claude Bernard Lyon 1, in the computer science department. I pursue my research at the LIP laboratory, located at ENS-Lyon, where I belong to the ROMA team.
Previously, between February 2019 and August 2019, I was a PostDoctoral Researcher at Universidad Jaume I in Spain in the High Performance Computing & Architectures group.
I obtained a master degree in computer science at ENSEIRB-Matmeca in 2015. From October 2015 to December 2018, I was a PhD student at Inria Bordeaux - Sud-Ouest, in the HiePACS team, where I was co-advised by Mathieu Faverge and Pierre Ramet. I defended my PhD thesis on low-rank compression for sparse direct solvers in November 2018 at University of Bordeaux.
