I am a teacher-researcher at Université d'Angers in the department of mathematics LAREMA since september 2024. I did my PHD under the supervision of Anne Pichon, professor at Aix-Marseille Université, and André Belotto, professor at Paris cité Université.
My research interests lie at the crossroads between complex analytic geometry, birational geometry, metric geometry, and topology. More precisely I am interested in studying the geometry and topology of singularities of complex spaces.
In my thesis I studied germs of complex analytic surfaces and Milnor fibrations from a metric viewpoint. For a presentation of my work, you can see my research statement.
Example of a singular space: The Whitney Umbrella in the real three dimensional space. The singular set is precisely the Z axis
Here is my CV and my publications:
