After several years of doctoral studies at the University of Mons on the subject of data quality in relational databases, I obtained in 2013 a PhD thesis entitled "Certain Query Answering in First-Order Languages". Since then, I have been a postdoctoral researcher at the University of Mons (Belgium) within the Software Engineering Lab. I authored many publications related to the maintenance and evolution of software ecosystems. My research work has focused in recent years on specifc topics related to software ecosystems, such as activity dynamics of open-source contributions and contributors, dependency-related issues in software packaging ecosystems, or dynamics of software package updates in such ecosystems.
