I look like this! Well, not everyday...
I am a research scientist in the Serena group, a joint team between Inria Paris Center and University Paris-Est, Cermics (ENPC).

My domains of interests are inverse problems and adjoint techniques. In particular, the refinement indicators algorithm which builds an adaptative parameterization of the distributed quantities to be identified. An interesting application is image segmentation.

Now, my main domain of interest is the use of functional programming for scientific computation, and more precisely to the OCaml language developed at Inria.
I am also interested in formal proof for scientific computing programs. I am a member of the ELFIC working group from Labex DigiCosme - Paris-Saclay that deals with the proof of correctness of a C++ library for the finite element method. These works follow former ANR projects CerPAN and Fost.

Software

Sklml: the OCaml parallel skeleton system, a functional parallel skeleton compiler and programming system for OCaml programs (easy coarse grain parallelization).
Ref-indic: Refinement indicators, an adaptive parameterization platform using refinement indicators (details only where they are worth it).
Ref-image: Image Segmentation by Refinement, image segmentation using optimal control techniques (no gestalt inside).
