Creative Mathematician


I am a creative mathematician. At the moment I am looking for a job in which I can combine my analytical and academic skills with my creativity. You can find my online CV here.

Below you can some of my projects, games and interests.

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


Unfortunately, these games are not for mobile phones.
Best played in Chrome or Firefox.


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!

This game was made in 72 hours for Ludum Dare 42, with the theme 'Running out of space'. 2018


The black hole at the bottom of the ocean is hungry! And she has very specific wishes too. Bring her the correct types and amounts of sacrificial plankton before your opponent does and before she changes her appetite.

This game was made in 48 hours for Ludum Dare 43, with the theme 'Sacrifices must be made'. 2018


In this local multi-player game, two robots race to find the most pairs of chips. Along the way they will find upgrades, portals and attacks.

This game was made with Rob and Wouter in 72 hours for Ludum Dare 41, with the theme 'Combine two incompatible genres'. 2018

I didn't know
we still had that

You probably have some stuff lying around in boxes that you haven't looked at for years! In this quick game you have to combine speed with memory. Can you find all the items in time?

This game was made in 72 hours for Ludum Dare 40, with the theme 'The more you have the worse it is'. Music by Otto Roth. 2017

Balls and Lines

The goal in this puzzle game is to connect ball the balls with a limited number of lines. Can you finish all the levels?

My first solo game! 2013


It's well past bedtime when a low rumble rolls through the streets of Friedrichshafen. Hindenboxer, a monster from ancient times, has awoken! Exploding zeppelin pilots scramble to combat the menace, but do they have what it takes?

This game was made with PlayCanvas in 72 hours for Ludum Dare 33, with the theme 'You are the Monster'. Special Guest: Otto as composer! 2015

The prime game

The idea of the game is simple: do you know if the given numbers are prime or not?

Stack the prime numbers on the left, and the composite numbers on the right.



A little game full of easter eggs.
How many easter eggs can you throw in the basket?

A small easter game made together with Wouter. 2017


Play with the variables and draw pretty patterns!

One of my earliest small projects with JavaScript. 2013


Prepare your sheep! Distribute a given number of actions over your sheep to get them to the flower.

This game was made for Mini LD 55, with the theme 'Preparation'. 2014


In this primitive drawing game, you can only draw using white and black circles. Let this restriction feed your creativity, and build your own snowman!

One of my first projects learning JavaScript, HTML5 and CSS. 2013

More games

Looking for more games? I started making games together with Jelle Nauta. In the beginning I mostly did graphics, music and sound, but later I started doing more and more programming. You can find our games here!

We participated many times in the Ludum Dare competition in 2013-2017.


Juggling act

For the annual dance performance of Addance, my dance teacher asked me if I wanted to make a juggling act. After many years of juggling, this is my first proper juggling act.

Siteswap Article

Together with Wouter van Doorn, I wrote a (Dutch) article about siteswaps in the Periodiek, the magazine of the study association Fysisch-Mathematische Faculteitsvereniging (FMF).


Siteswap Domino

For my juggling friends who like siteswaps. I made some domino-like cards in Inkscape. Print them out and try to make up the rules yourselves. :)

Unfinished. 2013


Below you can find my theses. You can find my publications here.

PhD thesis

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.

Master thesis

From finite automata to power series and back again.
Given a finite q-automaton over F_q with m states, what can we say about the algebraic degree of the corresponding algebraic power series over F_q? Conversely, given an algebraic power series of algebraic degree d, can we bound the size of a generating minimal automaton?


Bachelor thesis

Automorphism groups of cyclic codes.
Codes are used to store and send information. In this thesis we prove that the automorphism group of the binary Hamming code of length n = 2m − 1 is isomorphic to GL(m, 2). Next, we consider some transitive subgroups of S_n and give an application of automorphism groups to the minimum weight of a code.
