Curriculum vitae

I am a creative mathematician with a PhD degree in System Theory (Applied Mathematics). I like combining my analytical and academic skills with my creativity. At the moment I am working as a Data Scientist at Grain Data Consultants. Below you can find my CV, research interests and other interests.

Feel free to send me an email at or contact me through LinkedIn.

PhD degree in System Theory at the Jan C. Willems Center for Systems and Control of the University of Groningen, 2016.

MSc. Algebra & Geometry from the University of Groningen, 2012.

BSc. Mathematics from the University of Groningen, 2009.


Data Scientist

Grain Data Consultants

November 2018 - now

  • At Grain Data Consultants we help companies to collect, clean, store and analyze their online data. Examples of our customers are Ohra, Kaartje2go, NDC mediagroep and Hoogvliet.
  • One of my current projects is building a recommendation system for the websites of a newspaper publisher, based on Matrix Factorization and Personalized PageRank.
  • I work a lot with Splunk, which is a software platform to search, analyze and visualize machine-generated data.

PhD Candidate

University of Groningen

March 2012 - December 2016

  • During my PhD, I have studied the disturbance decoupling problem for linear multi-modal systems. We also studied the fault detection and isolation problem for bimodal systems and for systems defined over graphs. Finally, we studied a nonlinear consensus protocol with arbitrary sign-preserving nonlinearities.
  • I enjoyed teaching tutorials for several courses for Mathematics students: Linear Algebra 2, Metric Spaces and Analysis on Manifolds.


University of Groningen

Sept. 2007 - Aug. 2011

  • As a student-assistant, I taught several tutorials for bachelor courses at the Faculty of Mathematics and Natural Sciences, including Calculus, Vector Analysis and Linear Algebra.
  • Grading homeworks and (mid-term) exams was part of the job.

Making games
& Programming

  • You can find my small web games and other projects here.
  • I have participated many times in the online game making competition Ludum Dare. At first, I mainly focused on the artistic side of the game making process, but soon I started programming as well.
  • In my current job as a Data Scientist, I use python.
  • I started learning Java with the '30 Days of Code' challenge at HackerRank in november 2017.


  • Jugglers and mathematicians share the joy of discovering new patterns. There is even a mathematical way of describing juggling patterns, so called siteswaps.
  • Together with Wouter van Doorn, I wrote a (Dutch) article about siteswaps in the Periodiek.
  • I gave a talk on Siteswaps at the Radboud University of Nijmegen, at the 30th anniversary of DESDA (mathematics student association), April 16, 2016.
  • Santelli, the local youth circus, has a nice gym where I train and teach every week. I mainly juggle balls, but I also enjoy playing with clubs, diabolo and kendama.


  • I mainly practice contemporary dance and dance improvisation. I have also done ballet, some tap dance and modern jazz.
  • During the last ten years, I greatly enjoyed participating in several dance projects and productions. For example Globe Trot and Bries.


  • I started to play the violin during my sabbatical after my PhD. It is a very challenging musical instrument, but I greatly enjoy it.
  • Since January 2018, I also started playing the flute!
  • I enjoyed 12 years of piano lessons. I mainly play classical music, but also contemporary music. In 2010 I passed the EPTA grade D exam.

Leaf Blower

In this challenging and soothing game, you can play around with a leaf. Where will it take you?

Piggy Bank

As a piggy bank, your life is all about money. You need money to get higher up, but you also need money to extend your life. So choose wisely as you climb.

Ludum Dare 44, April 2019.


This game is about your personal space, your aura. Sometimes, you don't like other people to get too close, and you just want to scream: give me some space!
