Thomas Dufaud

Current position : Assistant Professor (Maître de Conférences) of University of Versailles (UVSQ) since September 2013

I received a Ph.D in Applied Mathematics from Claude Bernard University (Lyon 1) in 2011. I am assistant Professor and affiliated in Maison de la Simulation and LI-PaRAD laboratory where I am a member of the HPC Team. I authored 14 papers in international journals and conferences since 2010 and I am a co-advisor of 1 Ph.D since 2014. My main researches concern numerical linear algebra, parallel solvers and preconditioners, multilevel methods, and their application in the simulation of physical phenomenon. Since 2014 I also study software engineering for HPC and work on YML. In 2018, I am visiting scientist in the Programming Environment Research team in Riken R-CCS (Kobe, Japan).

I was in charge of the first year of the program MIHPS Msc in UVSQ (2014-2017)
