### Contact: arnaud.legrand@imag.fr ### Webpage: [Academic Page ](http://mescal.imag.fr/membres/arnaud.legrand/) ### Resume: Arnaud Legrand is the leader of the [POLARIS](https://team.inria.fr/polaris/) team. He is a [CNRS](http://www.cnrs.fr/) research scientist at the [LIG](http://www.liglab.fr/). His research targets the management (mostly from an algorithmic point of view, i.e., scheduling, load balancing, fairness, game theory….) and performance evaluation (in particular through simulation, visualization, statistical analysis, …) of large scale distributed computing infrastructures such as clusters, grids, desktop grids, volunteer computing platforms, clouds,… when used for scientific computing. He is one of the main developers of the [**SimGrid**](http://simgrid.gforge.inria.fr/) project, a **simulation** toolkit for building simulators of distributed applications (originally designed for scheduling algorithm evaluation purposes) developed in collaboration with [Henri Casanova](http://navet.ics.hawaii.edu/%7Ecasanova/), [Martin Quinson](http://www.loria.fr/%7Equinson/) and [Frédéric Suter](http://graal.ens-lyon.fr/%7Efsuter/). ### ### Education and Professional Experience Nov. 2015*Habilitation à Diriger des Recherches*, University of GrenobleOct. 2004-…:Tenured Researcher for the CNRS (*Chargé de Recherche*) at Laboratoire d'Informatique de Grenoble.2004-2005:Post-Doctoral Research Associate, UCSD (USA).
