Introduction
I did my Ph.D. from October 2010 to October 2013 at INPT-ENSEEIHT-IRIT, under the supervision of Patrick Amestoy (INPT-ENSEEIHT-IRIT) and Alfredo Buttari (CNRS-IRIT). My Ph.D. work focused on Block Low-Rank (BLR) approximations for multifrontal solvers. I coauthored a development version (not distributed yet) of MUMPS (MUltifrontal Massively Parallel Solver) embedding BLR techniques.

My main fields of interest are numerical linear algebra and high performance computing.
