Curriculum Vitae


Doctor in Mathematics, currently employed as system engineer of the high performance cluster at KU Leuven, and as visiting professor Mathematics at UHasselt, teaching Analysis and Linear Algebra. Looking out for new intellectual challenges. Area of interest: applied mathematics - machine learning - interface between system engineering and science. Father of Hester (2y) and Wannes (4m).

Competences and skills

  • Product owner: At KU Leuven, I am product owner for the central infrastructure with respect to research. This ranges from maintaining the high performance clusters, over issuing tenders for new clusters or storage, to working out solutions for research data management. I draw up the long-term strategy together with the stakeholders, and I translate this to short term plans and indicate which tasks are prioritized.
  • Expert: I started system management as a hobby, and trained myself to be an expert in this job. I mainly focus on tasks that require a bew approach - because there is no software available that meets the expectations, or because the existing software has certain restrictions. This ranges from custom software for the deployment of servers - because the existing solutions don’t scale or aren’t sufficiently safe - to software that is able to copy files efficiently from one parallel file system to another - because the existing tools would run 20 times slower and would not be ready inside a maintenance window.
  • Teaching: As visiting professor at UHasselt, I teach mathematics courses to students mathematics and computer science. During my PhD I translated abstract mathematics into a comprehensible talk aimed at different audiences.
