!!NEW!! The BOOM Project (Modeling and Opening Opinion Bubbles), supported by French ANR (2020-2024) has been accepted. Several positions (Master and PhD Thesis) are and will be available. Please contact me.

Associate professor – HDR (defended in April 2018) – in Computer Science (section CNU 27) at Université de Lorraine Since 2003.

Head of the BIRD research team at LORIA lab.

Teaching at IDMC (Institute of Digital Sciences, Management and Cognition), head of the 2nd year of Master in Cognitive Sciences (2012-2018: head of the Bachelor in Mathematics and Computer Science applied to Social and Human Sciences)

My research interests are: artificial intelligence, including user modelling: preferences and behavior for diagnostic, predictive and prescriptive modelling, with a specific focus on the design of recommender systems. My approach relies on machine learning and data mining.

I am currently the co-adviser of the following PhD students:

  • Patrick Asante Owusu « Causal inference for recommendation ». International co-tutelle with  Université de Sherbrooke (Québec), co-advised by Pr. Shengrui Wang. Defence planned in November 2023.
  • Alexandre Bettinger « Recommandation multi-acteurs pour la consommation de livres numériques en éducation ». Defence planned in November 2022.
  • Adrien Dufraux « Leveraging Noisy, Incomplete, or Implicit Labels for Automatic Speech Recognition ». Defence planned in November 2021.
  • Zhao Zhang  » Towards hybrid and explainable recommender systems mixing content analysis and collaborative filtering ». Defence planned in October 2021.
  • Halima Ramdani « Approche sémantique pour l’optimisation du processus de e-recrutement ». Defence planned in October 2021.
