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

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

Member of the KIWI research team at LORIA lab.

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:

  • 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.
