I am a full professor at Université Côte d'Azur, where my research affiliation is the I3S laboratory and my teaching affiliation is the Polytech Nice Sophia (PNS) engineer school.

I am vice-head of Wimmics, a joint research team between the I3S laboratory and the Inria center at UCA, part of the SPARKS pole. My research interests are in the field of Artificial Intelligence. My research topics are in the AI subfields of knowledge management and the semantic web. I am a specialist in graph-based knowledge representation and reasoning and interested in the development of hybrid intelligent systems combining KRR and machine learning techniques. My work aims at the extraction, integration, modeling, validation, and exploitation of web-based knowledge and resources for various epistemic communities. My main application areas are education, health, biological sciences, and digital humanities.

I lead the joint training program on Artificial Intelligence and Data Engineering (IAID) of the final training year of Polytech Nice Sophia (PNS) engineer school and the UCA master 2 in Computer Science. I am responsible of several courses related to my research domain (Web of Data, Semantic Web, Knowledge Engineering) in different French or international training programs, and general courses on databases. I am the pedagogical manager of continuing education for the Computer Science dpt of PNS.

From 2013 to 2021 I was board member of the French society for Artificial Intelligence (AFIA), treasurer from 2015. In 2015, I co-funded and led the AFIA college on Knowledge Engineering and I am now member of its steering committee.
