Topics of interest
My research interests include graph separators,
computational geometry, and algorithmics. I mainly work on three different
High-End Computing in connection with mesh generation
My PhD thesis deals with the various bottlenecks that appear using irregular
data structures in scientific computing. Along with a close modelization
of various popular kinds of scientific applications (and especially, the
resolution of large, sparse linear systems), new approaches are proposed
to take full advantage of the CPU resources. I am strongly concerned with
mesh generation in a parallel computing environnement.
Low-Earth Orbit (LEO) satellite networking
I am also interested in mobile telecommunications, and more specifically
those done by means of satellite constellations. More precisely, I am concerned
with the problem of routing a given set of communications through a network
in constant movement, such as a LEO satellite constellation with inter-satellite
links. In such an environment, I also foccus on energy-saving issues related
to on-board computations.
Optimization of telecommunication systems
Finally, I pushed forward my studies into the field of general optimization
for telecommunication systems. I am involved with algorithms and data
structures applied for instance to compression and coding. I also invest
myself in non-linear programming, such as semi-definite programming.
