About Me

I am a Research Associate (PostDoc) at the University of Luxembourg , conducting research at the intersection of software engineering, cybersecurity, and AI. I am a member of the Trustworthy Software Engineering (TruX) Research Group at the Interdisciplinary Centre for Security, Reliability and Trust (SnT) . My work mainly focuses on combining traditional software analysis techniques, such as static analysis, with newer AI methods, including LLMs, to make Android app analysis more practical, contextual, and useful for security tasks.

I obtained my Ph.D. from the University of Luxembourg under the supervision of Prof. Dr. Jacques Klein and Prof. Dr. Tegawendé F. Bissyandé .
