About me

Welcome to my homepage! I am a mathematician with a broad interest in engineering, applied and computational mathematics. My research is situated in Queueing Theory (a.k.a. The mathematics of queues). I am a proud member of the SMACS Research Group at Ghent University.

I'm especially interested in scheduling policies, with applications to computer systems, manufacturing systems, hospitals, and call centers.

In May 2022 I obtained a PhD in Mathematical Engineering at Ghent University, under supervision of em. prof. dr. ir. Herwig Bruneel, prof. dr. ir. Joris Walraevens and prof. dr. Dieter Fiems. An electronic version of my dissertation can be found here.

Publications

I am first author and principal investigator of the following four publications :

Talks

I try to attend one conference a year (that is relevant to queueing theory). I presented my research at four international conferences :

  • 13th International Conference on Queueing Theory and Network Applications, Tsukuba (Japan), 2018-07-25. Received the best Student Paper Award.
  • 14th International Conference on Queueing Theory and Network Applications, Ghent (Belgium), 2019-08-27.
  • 31st European Conference on Operational Research, online event, 2021-07-13.
  • 32st European Conference on Operational Research, Helsinki (Finland), 2022-07-06. [Slides]

Teaching

I would dare to say that I enjoy teaching almost as much as I enjoy my research. In the previous years, I took care of the teaching tasks for several exercise classes.
