Currently a PhD student at the University of Stuttgart, advised by Prof. Dr. Michael Pradel. I hold an Engineering degree from École Supérieure d’Informatique (ESI, ex. INI) since 2020. Previously, I worked as a research engineer in artificial intelligence and data science at the Multidisciplinary Institute for Artificial Intelligence, Grenoble, France. My research interests include AI4SE, bug finding in software/systems, and automation of testing and software analysis.
