I am interested in complex relationships: high dimensionality (hypergraphs, d-lattices) or complex models (relational models). I'm interested in the theoretical aspect of those complex structures.
I also try to look at interesting patterns in data on graphs or hypergraphs using symbolic approaches from formal concept analysis and numerical approaches such as graph signal processing.
I am interested in applications using these discrete structures in software engineering and healthcare.

Since November 2020, I am co-supervising Boubou Thiam Niang with Jannik Laval and Nawel Amokrane, between DISP lab and Berger-Levrault. Since October 2023, I am co-supervising Randa Cheima Bendjeddou with Tao Wang and Aicha Sekhari with a government grant (bourse ministérielle).

I am part of the DigiHealth-Asia Erasmus+ project, together with teams from 9 other universities. The project aims at developing digital health solutions in Mongolia, Thailand, and Pakistan, and the corresponding university courses in those countries. Interesting, right? I act as local coordinator for the Lyon 2 team. More information on the project's website!

I am part of the team of local organizers for ESUG 2023. I am a PC member for OrMeKR (Ordinal Methods for Knowledge Representation and Capture), a workshop at K-CAP 2023 and PreSCoD (Preprocessing and Scaling of Contextual Data), a workshop at ICFCA 2023. I am also an organiser for workshop on Data and AI in Health, in Lyon.
