I'm Mathematics teacher in classe préparatoire BCPST1 at the Lycée Hoche in Versailles. Before, I was postdoctoral researcher at the Universität Duisburg-Essen in Germany in the group of Prof. Dr. Jochen HEINLOTH and I defended my Ph.D. thesis on June 25, 2018 at the Institut Fourier in Grenoble under the supervision of Philippe EYSSIDIEUX.

Last update: September 2023.

Other activities at the Université Grenoble Alpes

Ph.D. seminar

With Alejandro RIVERA we organized in 2016–2018 the Ph.D. seminar of the Institut Fourier. Every week a speaker, from the Institut Fourier or from the outside, is invited to talk about a subject of his choice (not necessarily related to his research) in an understandable way for our Ph.D. students.

Working groups

With Pedro MONTERO we organized every year our own working group for PhD students. The goal is to read a book together with one talk a week, on a quite large topic around complex algebraic geometry.

Other skills

Languages

French (native language), English, German, Italian.

Computer

Strong interest for GNU/Linux systems and free softwares in general, notably: Debian GNU/Linux distribution, GNU Emacs editor, C and Python languages.

Teaching: Python.

Recent interests: clavier BÉPO (French-speaking ergonomic keyboard layout), Typst (new typesetting language, potential successor to LaTeX, written in Rust language).

Personal

On Summer I go surfing waves. For this I traveled to Portugal (Peniche, Summer 2013, Summer 2014, Spring 2018), to Morocco (Imessouane, Summer 2015), to Indonesia (Bali, Summer 2016), and I'm used to going to the French South-West coast (Vieux-Boucau is my home spot). I also traveled to Chile (Valparaíso, Summer 2019) and to the United States (Miami, Spring 2022).

Image: Couple dance I'm learning and practicing regularly latin couple dances, Salsa and mainly Bachata. I participated to dance festivals in Düsseldorf (March 2019, February 2020), Lyon (April 2019), Cologne (October 2019), Amsterdam (November 2019, November 2022, July 2023), Prague (February 2020), Luxembourg (December 2022).
