I am a postdoctoral researcher at the Kurt Gödel Research Center, which is part of the Faculty of Mathematics of the University of Vienna. I am working in Benjamin Miller's team.

My research interests are mostly Ramsey theory, functional anaylsis (especially Banach-space geometry), and set theory (especially determinacy and descriptive set theory).

My CV is available here.

I am launching a project aiming to create a database of classical and exotic Banach spaces. See this document for more information. This is a collective project, please contact me if you want to contribute!



Ph.D. thesis

I did my Ph.D. in the mathematical logic team of the IMJ-PRG, at the University Paris Diderot. My supervisor was Stevo Todorcevic. The title of my thesis is "Ramsey theory without pigeonhole principle and applications to the proof of Banach-space dichotomies"; I defended it on June 28, 2018. The manuscript is available here (only the short introduction is in French; you will find a short summary in English on page 3).

In France, Ph.D. thesis manuscripts are peer-reviewed. Here are the reports of the referees:

The report of my defence is available here (in French).

Teaching

I am currently not teaching. You will find below a list of my previous teaching duties.


In 2018–2019, I was an Attaché Temporaire d'Enseignement et de Recherche (assistant professor) at the University Paris Diderot. I taught the following:


From September 2015 to August 2018, I was a moniteur (teaching assistant) at the Department of Mathematics and Applications of the École normale supérieure in Paris. I taught exercise sessions in mathematical logic. My exercise sheets (in French) are available on this page.
