After graduating from the MVA Master 2 in the summer 2015, I am currently in the third year of my PhD under the direction of Alain Trouvé at the ENS of Cachan. I am also employed as a "Caïman" (tutor and teaching assistant) by the École Normale Supérieure, in the Department of Mathematics.

I am mainly interested in shape analysis, focusing on Riemannian methods such as LDDMM deformations and optimal transport plans. Here is a CV.


I have been playing the flute for 11 years at the Conservatoire Paul Dukas, in Paris. I especially enjoy playing baroque music : J.S. & C.P.E. Bach, J.J. Quantz, G.P. Telemann...

My other interests include ancient history, Chinese culture and pedagogy. Here are some books that I would strongly recommend:
