François Tessier has been a Research Scientist at Inria (Rennes, France) since November 2020. He received a Ph.D in Computer Science in 2015 from University of Bordeaux, France, under the supervision of Emmanuel Jeannot and Guillaume Mercier. His thesis focused on topology and affinity-aware process placement and load balancing algorithms for large-scale applications. From 2016 to 2018, he was a postdoctoral appointee at Argonne National Laboratory, IL, USA, within the LCF division (Leadership Computing Facility) where his research work has been more oriented towards I/O optimization in parallel libraries. Before joining Inria, he was a Computational Scientist at ETH Zürich within CSCS (Swiss National Supercomputing Center) located in Lugano, Switzerland, where he addressed the problem of dynamically provisioning of storage resources for HPC applications and large-scale workflows on supercomputers. At Inria, he is now working on various I/O and storage challenges in a context of HPC/Cloud convergence.
