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 a PhD student in mathematics of the Université de Haute-Alsace under the supervision of Pr. Abdenacer Makhlouf.

News

The second edition of the MAThEOR Days will take place 10-12 July 2024! Registration on the webpage of the event.

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

I am co-organizer of the Conference Algebra and Deformations that will take place June 17-21 in Mulhouse, France.

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.
  • 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.
  • The above diagram represents the first terms of the restricted complex of cochains in the case where the restricted Lie algebra L is abelian.
