Jonas Seiler

Hallo from Germany!

I'm Jonas, a puzzle enthusiast, cake lover and more recently, an ESA Graduate Trainee.

Before I joined the Advanced Concepts Team, I completed a Bachelor of Science in Theoretical Computer Science and a Master of Science in Mathematics at the Karlsruhe Institute of Technology (KIT), minoring in the respective other field. During my studies and now, I try to balance on the edge between theoretical computer science and mathematics and supplement problems and theory of one field with methods and tricks from the other.

If you plan to nerd snipe me, your best bet are decision problems and algorithms for graphs and other combinatorial objects. I am also interested in algebraic topics like computational and geometrical group theory, algebraic topology and category theory.

In the future, I wish to explore some newer methods in the world of informatics like randomization and distributed computing.

Whenever I am not working (which might also happen during working hours), you can usually find me solving logic puzzles, folding origami or playing board or video games.

Here are some stats about me:

• Last year, I solved 2436 logic puzzles
• I am playing with Hanabi Level 14 conventions
• I have driven 2200 kilometers with my bycicle in 2025
• The best SCP is SCP-7179

On the left you can find an example of a logic puzzle (Akari) I like, here are its rules:

• Place lightbulbs on some white cells to light all remaining cells.
• A lightbulb illuminates its row and column until stopped by a black cell or the edges of the grid.
• Bulbs may not illuminate each other but an empty space may be illuminated by more than one bulb.
• Numbered black cells must touch exactly that number of lightbulbs in the four neighboring cells.
• Unnumbered black cells can touch any number of lightbulbs.
