Research interests: Nonlinear dispersive equations, in particular: collisions, well-posedness, stability and asymptotic
stability and blow-up.
I obtained a Ph.D. in Mathematics at the University of Versailles Saint-Quentin, under the advise
Martel (Video) and Frank Merle (Video 1,
to be held at Universidad de Chile, Santiago, on December 4-7 2017.
