Short Bio:
Since 2010, I have been working at the SnT center of the University of Luxembourg, first as Research Scientist (from 2010 to 2015), then as 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).
Together with my colleague Prof. Bissyande, we are heading the TruX research group.
Since Oct. 2018, I'm a member of the University Council of the University of Luxembourg as 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.
Grants:
I am/was Principal Investigator on a dozen of projects including industrial partnership projects. I acquired more than 5 million euros of project funding
(mainly through projects funded by the Luxembourg Research Agency, the European Commission, and industrial partnerships). The full list of acquired grants could be found here.
