Short Bio


Mathias Jacquelin is a research scientist in the Scalable Solvers Group in the Computational Research Division at the Lawrence Berkeley National Laboratory since November 2015. He is currently working on highly scalable algorithms for solving large sparse symmetric linear systems.

He obtained a Master’s Degree in Computer Science from INSA of Lyon, France (National Institute of Applied Sciences). He went on to the Ecole Normale Superieure of Lyon, to complete his Ph.D. in Computer Science, focusing on algorithms and scheduling, and how hierarchical memory architectures should be handled. He joined Laura Grigori's team at INRIA of Saclay, France, for 18 months, working on communication avoiding algorithms for dense linear algebra. He then joined LBNL in 2013 as a postdoctoral fellow in the Scietific Computing Group and then the Scalable Solvers Group, focusing on various sparse linear algebra computations.
