Research

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.

Student supervision

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).

Projects

I am also part of the HarmonicAI MSCA staff exchange project (2024-2028).

I am part of the DigiHealth-Asia Erasmus+ project (2021-2025), 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? More information on the project's website!

Committees

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.
