Short Bio:
Since 2010, I have been working at the SnT center of the University of Luxembourg,
first as a Research Scientist (from 2010 to 2015), then as a Senior Research Scientist (Faculty position, from 2015 to 2019),
and as Chief Scientist I (Associate Prof., from 2019 to 2022).
Finally, in January 2023, I was promoted to full professor (Chief Scientist II).
With my colleague Prof. Bissyande, we are heading the TruX research group.
Since Oct. 2018, I have been a member of the University Council of the University of Luxembourg as a representative of the Interdisciplinary Centers Professors.
From August 2021 to May 2022, I was a visiting scholar at the University of Washington, Seattle, in the PLSE group (mostly working with Prof. Mike Ernst and Prof. René Just).
Research interests:
I am working in Software Engineering and Software Security, with a specific focus on:
Program analysis -- applied to mobile security,
Software debugging -- especially bug localization and program repair, and
NLP and AI for software engineering -- especially to devise new code representation techniques.
