I am currently a postdoc at the Université de Lorraine/Goethe Universität Frankfurt, funded by the ANR-DFG POK0, mentored by Gianluca Pacienza and Alex Küronya .
Previously, I was a postdoc in Institut de Mathématiques de Jussieu-Paris Rive Gauche (IMJ-PRG), Université de Paris, funded by the ERC Synergy Grant HyperK, mentored by Olivier Debarre .
Before I was ATER (teaching and research assistant) at the Institut de mathématiques de Toulouse, Université Paul Sabatier.
I obtained my PhD in Mathematics at Université de Poitiers in october 2020 under the supervision of Alessandra Sarti. Click here for a detailed CV.
My research field is complex algebraic geometry. More precisely, I work mostly on Hyper-Kähler manifolds and their interplay with other geometric objects, in particular:
Moduli spaces, Kodaira dimension, cones of divisors, relations with modular forms;
Extrinsic geometry, linear systems, Fujita's Conjecture, projective models;
birational geometry, biregular and birational automorphism, birational models, MMP;
locally complete families of Hyper-Kähler manifolds, such as EPW sextics, and their relation with Fano varieties;
cohomology of Hyper-Kähler manifolds.
