I am a PhD student in IRMAR (University of Rennes) and Institut Fourier (University of Grenoble Alpes), since September 2021.
I work under the supervision of Michel Brion and Matthieu Romagny.

My research is mainly about the geometry of projective homogeneous varieties over fields of positive characteristic.
Related subjects I am interested in are birational geometry and representation theory of reductive groups.

My first projects were about classifying non-reduced parabolic subgroups in small characteristics.
Here is my CV.
