Najib Idrissi’s math page

Intro

I am a maître de conférences at the mathematics department of Université Paris Cité. I am a member Institut de Mathématiques de Jussieu–Paris Rive Gauche (IMJ-PRG) and deputy head of the team-project “Algebraic Geometry & Topology” (TGA).

I am the scientific coordinator of the ANR Young Researcher project “Structure and Homotopy of Configuration Spaces” (SHoCoS).

You can find more information in my CV.

My main mathematical interests are in the fields of operads, as well as in their applications to algebraic topology and homological algebra. I am especially interested in the study of configuration spaces of manifolds, their links to graph complexes, and the invariants they define. These days, I am also interested in the representation stability phenomenon.

My full last name is “Idrissi-Kaïtouni” and you may find this spelling in some places, e.g., my email address.
