Post-doc in Mathematics

I am a post-doctoral researcher in mathematics at New York University Abu Dhabi under the supervision of Pr. Sofiane Bouarroudj.

Before that, I was a PhD student in mathematics of the Université de Haute-Alsace under the supervision of Pr. Abdenacer Makhlouf.

Address: Division of Science and Mathematics, New York University Abu Dhabi, P.O. Box 129188, Abu Dhabi, United Arab Emirates (here).

Here is my CV (October 2024).

Here is my page on ResearchGate.

My ORCID number is 0009-0004-2629-4518.

I speak French (mother tongue), English (professional and colloquial) and German (intermediate). I also have (very) basic notions of Arabic.

News

The second edition of the MAThEOR Days took place 10-12 July 2024!

In February 2024, I obtained my national scientific qualification as associate professor ("Qualification aux fonctions de Maître de Conférences", Section 25)

In October 2023, I started my post-doc with Sofiane Bouarroudj at New York University Abu Dhabi.

Scientific interests

My scientific interests lie mainly in the domain of non-associative algebras, with a focus on restricted Lie and Lie-Rinehart (super)algebras over fields of positive characteristic.

During my post-doc, we are interested in the following topics:

  • Restricted cohomology of restricted Lie superalgebras;
  • Classification problem of restricted nilpotent Lie superalgebras of small dimension;
  • Restricted Lie-Rinehart and Poisson (super)algebras in characteristic p=2;
  • Double extensions of Lie superalgebras in various settings;
  • Connections on Lie superalgebras in characteristic 2 and Lagrangian extensions.
  • During my thesis (manuscript in French), I was interested in the following topics:

  • Deformation theory of Lie-Rinehart superalgebras over characteristic zero fields;
  • Computer-aided classification of Lie-Rinehart superalgebras over the complex field;
  • Restricted cohomology of restricted Lie algebras over positive characteristic fields;
  • Restricted formal deformations of restricted Lie-Rinehart algebras over positive characteristic fields;
  • Representations of restricted Lie-Rinehart algebras;
  • Double extensions of quasi-Frobenius restricted Lie superalgebras.
