I am a PhD student in Mathematics at the Université de Neuchâtel. I'm doing my PhD under the supervision of Prof. Felix Schlenk.

Research
I work on problems in symplectic topology. More specifically, I'm interested in embedding problems in symplectic topology and in exploring the behavior of symplectic embeddings of rational homology balls and their Lagrangian skeleta.
