About Me

Caren Al Anaissy

I am a Postdoctoral Researcher at LIP6, Sorbonne Université (Paris) in the Multiagent Systems (SMA) team, under the supervision of Nicolas Maudet.

My work is funded by the PEPR eNSEMBLE project and is part of the PC4 CONGRATS: "Collaboration à grande échelle". My research focuses on intelligent facilitation of deliberation in online debates, exploring AI-driven approaches to enhance decision-making in e-democracy.

This work involves computational argumentation, natural language processing, and human-computer interaction to design more effective deliberative platforms.

I obtained my PhD in 2024 from Centre de Recherche en Informatique de Lens (CRIL), Université d'Artois, Lens, France.
