I have been a Research Scientist at Inria in Rennes, within the KerData team since November 2020. I have been focusing there on I/O and storage challenges in a context of HPC/Cloud convergence. Before that, I stayed two years as a Computational Scientist at ETH Zürich within CSCS (Swiss National Supercomputing Center) located in Lugano, Switzerland where worked on dynamic resource provisioning for HPC applications and large-scale workflows. Previously, I spent two years and a half as a postdoctoral appointee at Argonne National Laboratory, IL, USA where I addressed the problem I/O optimization. I received a Ph.D in Computer Science in 2015 from University of Bordeaux, France, under the supervision of Emmanuel Jeannot and Guillaume Mercier. My Ph.D thesis focused on topology and affinity-aware application placement and load balancing.
My research interests are mainly around I/O optimization and the efficient use of storage resources on large-scale systems. I am also interested in topology-aware placement techniques.

Major Software Developments
Intermediate Storage As A Cache (ISAAC) : Lightweight library implementing a wrapper of standard MPI-IO calls. Targeting supercomputers with node-local storage (HDD, SSD), ISAAC can take advantage of this memory layer and use it as a transparent cache to significantly improve the I/O bandwidth.
TAPIOCA : Topology-aware data aggregation C++ library for I/O intensive applications.
TreeMatchLB : Set of topology-aware load balancing algorithms developed for the Charm++ runtime system including TMLB_TreeBased, a highly-scalable hierarchical and distributed load balancer targetting communication-bound applications.
TreeMatch : Algorithm and tool to find a good process placement according to the communication pattern of an application and the target architecture. Project initially developed by Emmanuel Jeannot and Guillaume Mercier.
