Associate Professor of Software Engineering at INSA Rennes - Research in the DiverSE Team, IRISA, Inria, Univ Rennes, CNRS - France
About me
Hello 
, I’m associate professor of Software Engineering at INSA Rennes.
I’m doing research in the DiverSE Team in the IRISA/Inria lab at Rennes in France.
I’m also in charge of corporate relations for the Computer Science department at INSA Rennes (responsable des relations entreprises pour le département Informatique de l’INSA Rennes).
My research interests are the following:
- Software Energy Consumption and Green IT
- Empirical Software Engineering
- Software Metrics and Quality
- AI for Software Quality
Currently, I’m working on the energy consumption of the software supply chain (CI/CD and build managers) used in the DevOps loop. These systems are interesting to study due to their massive, automatic, and frequent use in DevOps. Supply chains use various tools to build software, and their high configurability gives them a special status in the software world. My research consists of finding solutions to reduce the consumption of DevOps tools and providing developers with a perception and evaluation of the software energy consumption in the DevOps loop. To achieve this, I employed a mining software engineering approach to collect and evaluate tools used in the DevOps world at a large scale.
I obtained my Ph.D. in 2021 from the IMT Mines Alès (France) under the supervision of Christelle Urtado and Sylvain Vauttier.
