Jean-Michel Gorius
Jean-Michel is a Ph.D. student at the University of Rennes. He is working at the Institut de Recherche en Informatique et Systèmes Aléatoires (IRISA) in the TARAN team, lead by Olivier Sentieys. His Ph.D. work revolves around the High-Level Synthesis of Instruction Set Processors and is supervised by Steven Derrien (University of Rennes) and Simon Rokicki (ENS Rennes). He received his Bsc. and Msc. degrees from the University of Rennes, and his Magistère degree from ENS Rennes.
Jean-Michel's research interests range from hardware design and hardware synthesis to compilation and high-performance applications. He led the initial development of a compiler intermediate representation for stencils based on MLIR at ETH Zürich, under the supervision of Tobias Grosser. As part of this project, he has been working in close collaboration with ETH Zürich, CSCS, MeteoSwiss and Vulcan Inc.
Besides computer science, Jean-Michel enjoys playing the piano, riding his bike and hiking.
