Research interests
My research interests cover the applications of applied mathematics, with a particular emphasis on
- signal and image processing and extraction of information from images,
- applications to biology.
I am also interested in theoretical aspects (numerical schemes for PDEs, nonlinear optimization in large dimension). My activities can be classified in the following items (follow the links for illustrations, and see the papers for more details):
