Short bio

I received a Ph.D. in Computer Science (december 2001) from Université Henri Poincaré, France, INRIA Lorraine. After spending two years at UC Berkeley and LBNL as a postdoctoral researcher, I have joined INRIA in january 2004. I was a member of Sage group at INRIA Rennes and Grand-Large group at INRIA Saclay - Ile de France and LRI, Paris 11 University. Since January 2013 I am leading Alpines, a joint group between INRIA Paris - Rocquencourt and J.L. Lions Laboratory, UPMC.
During the academic years 2014/2016 I was on a sabbatical leave / long mission at UC Berkeley.

Distinctions and awards

  • SIAM Siag on Supercomputing Best Paper Prize 2016 for the most outstanding paper published in 2012-2015 in a journal in the field of high performance computing. With J. Demmel, M. Hoemmen, and J. Langou for the paper Communication-Optimal Parallel and Sequential QR and LU Factorizations, published in SIAM Journal on Scientific Computing 2012.
    Citation of the jury: This is a cornerstone paper in Numerical Linear Algebra and Parallel Processing that lays down both theoretical and practical algorithmic frameworks for communication-avoiding algorithms. The paper provides powerful insights and renews attention on communication reduction both of which will have long-lasting and practical impact in parallel and distributed computing.
