About me
I am a PhD student at École doctorale Galilée under the supervision of Pascal Boyer (Université Sorbonne Paris Nord).
I am a member of the AGA team in Laboratoire Analyse, Géométrie et Applications (LAGA).
I am interested in number theory and arithmetic geometry. More specifically, my research revolves around the cohomology of Shimura varieties.
Here is my Curriculum Vitae.
