ANL - LCF Division

I am a postdoc at Argonne National Laboratory, IL, in the LCF division since February 2016. I received a Ph.D in Computer Science in 2015 from University of Bordeaux, France. My works have been focused on topology and affinity-aware application placement and load balancing. My advisors were Emmanuel Jeannot and Guillaume Mercier.

I am now working on the consideration of data locality in several topics : process placement, load balancing and parallel I/O.
