I am a maître de conférences (MCF) in algebraic geometry at the Institut de Mathématiques de Bordeaux.
I am a member of the Number Theory Group (Équipe de Théorie des Nombres).
I am the PI of the ANR JCJC FRACASSO project.

14th swiss-french workshop in Algebraic Geometry, Charmey (CH), 13 - 17 January 2025;

From February until August 2025 I am on sabbatical !

My research interests are in birational geometry, especially

During the academic year 2018/19 I was a FMJH post-doc in algebraic geometry at the Laboratoire de Mathématiques de Versailles, Université Paris Saclay, funded by the Programme Sophie Germain. I was a member of the Algebra and Geometry team and my supervisor there was Nicolas Perrin.

In the period Sep 2016 - Aug 2018 I was a postdoc at the Mathematisches Institut, HHU Düsseldorf, where I was a member of the Algebra and Number Theory research group. My supervisor there was Benjamin Klopsch.

During the academic year 2015/16 I was a postdoc at the Mathematisches Institut, Universität Basel, where I was a member of the Algebra and Geometry research group. My supervisor there was Jérémy Blanc.

I obtained my PhD at the Department of mathematics, Imperial College London. I was a member of to the Geometry group and my supervisor was Paolo Cascini. During the last months of my PhD, I visited IMPA for the Thematic Program on Algebraic Geometry.
