Hi! I'm Luc, a Dutch computer scientist with a research focus on formal methods, concurrency and formal languages. More specifically, I'm working on the theoretical foundations of designing distributed systems, and choreographies in particular.

I enjoy twirling my moustache, showing people my amazing Obelix mug (no relation to the moustache), staring at a (chalk or white) board or the ceiling (whichever feels more productive), and chatting with colleagues and students. Outside of work, I also enjoy playing board and video games, watching films, bowling, walking or cycling around in various bodies of nature, observing animal behaviour, hugs, eating good food, listening to water in motion, reading various comics and novels, visiting new places, and generally lazing about, enjoying life — preferably with a hat, in the sun, and in friendly company.

I'm currently looking for positions; I warmly welcome suggestions!

Bio

From September 2019 to May 2024, I was a PhD student at the Open University of the Netherlands, under the supervision of Sung-Shik Jongmans. I defended my thesis, titled Expressive specification and verification of choreographies, in December 2024. I'm happy to share a recording of my layman's talk with those interested; just send me a message!

From July 2022 to January 2025, I was a lecturer at the Leiden Institute for Advanced Computer Science.

From April to June 2025, I was a postdoc researcher at the University of Southern Denmark, as part of the DDCxTrygFonden fellowship at the Digital Democracy Centre, and working with the Department of Mathematics and Computer Science.
