Hi! I'm a research engineer with the LIP laboratory at Éns de Lyon. I share my worktime between the laboratory IT management team (MI-LIP) and the Arénaire research team.

My main research topic is function approximation by polynomials and rational fractions. More precisely, I apply linear programming tools to the search of optimal “constrained” (e. g. bit size) polynomial coefficients. Most of this work has been done in support of Nicolas Brisebarre, Sylvain Chevillard, Christoph Lauter and, more recently, Mioara Joldes own research.

My favorite gears for this kind of work are PIP and GLPK. I also extensively use Sollya, as mostly everyone in the team. MPFR is an unavoidable tool of the trade for anyone who deals high-precision numerics. When time allows, I give a flick of upgrade to Nathalie Revol's MPFR++, a C++ interface to MPFR (yeah, it's been long since last time). PERL and Bash are my prefered brands of glue for software.

Some of the code I've put up together can be found under the MEPLIB project (badly out of sync too!).

For IT management duties, my MI-LIP buddies are Jean-Christophe Mignot and Dominique Ponsard and we run a mostly Debian shop here.
