Current job
Assistant Professor in statistics since September 2019 at the University of Evry Paris-Saclay in the laboratory LaMME. My current research focuses about change-point detection. With my collaborators, I develop the following research directions:
- Algorithmic efficiency: dynamic programming methods (functional pruning; DUST and FOcUS algorithms);
- Extensions to complex data lying in non-Euclidean spaces (Fréchet means in Hadamard and CAT(k) spaces);
- Computational geometry (convex hulls; shape coverings and intersections).
As an Applied Mathematician, I like to work at the interface of different fields. My current and past interests are:
Statistics : Change-point detection
Optimization : Constrained Optimization, Convex optimization, Computational geometry, Quadratic and linear programming.
Numercial analysis : Quasi-Newton algorithm
Package development : gfpop, dust (see github)
In particular, I have a strong interest in problems that require the development of new optimization tools.
