He obtained his Ph.D. in 2005 from the University of Nancy, France, where he worked on concrete applications of semantic technologies in the medical domain. He is now leading research around concrete solutions for the realization of intelligent systems producing and consuming knowledge from the semantic web, with applications in education, personal data management, and smart cities.

Mathieu has authored more than 120 publications in leading journals and conferences in the field, and has led the development of some of the most innovative systems and services in the semantic web area, including the semantic web search engine Watson, data.open.ac.uk, the worldwide first linked data platform of a university, and the MK Data Hub, a smart city infrastructure for data curation, integration, and analysis. In 2011, he was recognized as one of the ten most promising young researchers in artificial intelligence, through the "AI 10 to watch" award from the prestigious magazine IEEE Intelligent Systems, and has won numerous other awards especially related to innovative applications of semantic technologies.
