Thomas Alazard

FMJH Fondation mathématiques Jacques Hadamard

I am in charge of the following program:

• Sophie Germain master's scholarships and Phd track scholarships.

  The Mathematics Foundation Jacques Hadamard (FMJH) offers scholarships for excellence for one or two years to French and foreign students. There are two calls for applications.
