Introduction

Welcome on my personal webpage. My name is Julius Krebbekx. I was born and raised in The Netherlands, where I have lived in various places in Noord-Brabant and Limburg throughout my childhood. Nowadays, I live in Eindhoven.

I am currently a PhD student at the TU/e in the Control Systems group. On my webpage, you can find information about my PhD research, side projects, and other things that I enjoy. Feel free to contact me about anything that you read here!

Background info

I am a (theoretical) physicist and mathematician by training. I have obtained by BSc in physics at the Eindhoven University of Technology (TU/e) and my MSc mathematics and MSc theoretical physics from Utrecht University. My main interests are:

• Quantum mechanics (condensed matter, quantum gases, quantum field theory),
• Dynamical systems and mathematical system theory (control systems, PDEs, functional analysis, chaos, mathematical neuroscience),
• Numerical methods and scientific programming (nonlinear programming, genetic algorithms, simulation).
• Programming. I think that C/C++ is the most elegant and rigorous way to write software. Julia is a language that I am excited about. The package management is really good, compared to Python, but it has many immature packages. Since I work in the control systems community, I unfortunately use MATLAB frequently. I got into the basics of HTML/CSS the moment I decided to hack together this website :).

In my spare time, I like to play the piano, do some sports (cycling, golf, skiing), ride my motorcycle, and read a book. Examples of an ideal vacation are camping, skiing in the mountains or going on a (multi-day) hike.

Random stuff

• In particular for people who work or study at the TU/e, I would recommend visiting the TU/e encyclopedia website. It is maintained by enthousiastic (former) employees of the TU/e, and you can find many interesting and unexpected facts and stories about our university.
• Intesesting and fun mathematical theorems and puzzles.
  • Ham sandwich theorem: suppose you have a sandwich containing of bread, ham, cheese and another slice of bread. The theorem proves that you can always cut any such sandwich in two pieces with equal amount of bread, ham, and cheese.
  • Riddle about interesting ways to cut pizza: can you cut a pizza in identical pieces, such that half of the pieces contain no crust?
