I am currently a professor cat 2 (~associate professor) at Ăcole de Technologie SupĂ©rieure, an engineering university of the UniversitĂ© du QuĂ©bec system.
Prior to that, between 2010 and 2021 I was an assistant professor at University Sorbonne Paris Nord. I was, and am still a member of the AOC team of the LIPN. From Sept 2019 through Aug 2021, I was on a sabbatical (délégation CNRS) at the University of Oregon. I stayed in Oregon until the end of 2021 as a research associate, and I spent a year at Université du Québec à Montréal (UQAM) in 2022.
In 2009-2010 I worked as a post doc in the HPC group of the Iowa State University of Science and Technology. I worked for the Department of Mathematics under the supervision of Glenn Luecke. Prior to that I was a PhD student in INRIA's Grand Large team. My advisor was
Franck Cappello. I was part of
the Parallelism
team of the Laboratoire de
Recherche en Informatique
of University Paris-Sud in
Orsay. I was also a visitor
at the Innovative Computing
Laboratory, where I worked
with George
Bosilca, Aurélien Bouteiller and Pierre Lemarinier in the
MPI group of Jack Dongarra's team. Even before, I did an internship in the Department of Mathematics of King's College London, where I worked with Peter Sollich.
My academic genealogy, obtained for the Math Genealogy project using Mathematics Genealogy Grapher. My Erdos number is 4, through multiple paths: Erdos -- Alon -- Tixeuil -- Peyronnet -- me, or Erdos -- Graham -- Rosenberg -- Cappello -- me, or Erdos -- Hell -- Bampis -- Finta -- me, or Erdos -- Janson -- Lavault -- Butelle -- me.
My ha-index is 77, which is considered as "needs to be improved", but I don't think I can improve it anymore.

I am an active member of the International
Working Group on Cloud Computing Resiliency (IWGCR). The
International Working Group on Cloud Computing Resiliency (IWGCR) is a
working group with a mission to monitor and analyze Cloud Computing
resiliency. The working group is composed of I.T. Executives, academic
researchers and industry representatives.
In March 2012 the IWGCR released a report presenting the downtime
statistics of current cloud solutions and rankings of the reliability
of the solutions that are currently available on the cloud
market. New reports were published in June 2013 and in March 2014.

I developped a program that computes a player's future ranking in
the French Tennis system.
The French tennis ranking system works with points: if you win agains
a player whose ranking is higher than yours, you get more points than
if your opponent has a lower ranking than yours. The tricky part is
that the ranking that is taken into account is not the one that your
opponent had the day you played against each other, which would be too
easy. It is the one you opponent will have for the next season. So you
need to know what your opponent's future ranking to make an estimation
of your future ranking.
In practice, the French Tennis Federation makes multiple computations
(30 to 35) until the computation stabilizes, with an algorithm that
fixes oscillations.
As a consequence, in order to have a precise idea of their
future ranking, players need to looks at their opponents'
palmares, then their opponents' opponents' palamres, etc,
recursively, until all the connected component of the graph has been
explored.
The program I have developped performs requests on the Web server of
the French Tennis Federation and makes a recursive exploration of the
matches that involved a player and their opponents, to make a
recursive estimation of his/her future ranking. The computation stops
at a given depth, which is chosen by the user of the program. The
deeper you go, the more precise and reliable the estimation will be.
This program is available (under CeCILL-C and LGPL licence) on
GitHub.
