I moved from Münster to Karlsruhe to Freiburg to Paris to Freiburg to Osnabrück and I did maths in each town. On my way, I've also seen some philosophy, computer science and physics. Right now I'm working mostly on algebraic geometry and homotopy theory, as I already did for my diploma and my PhD thesis. I defended my thesis in 2016.

You can read more details about my PhD project here.

I keep a list of academic events I attended.

Serious preprints can be found on the arXiv.

I'm (passive) member of the DMV (german math society), EMS (european math society), Mieterverein, and Bündnis '90 Die Grünen. I was stipendiate of the Studienstiftung des deutschen Volkes (german national merit foundation) during my undergrad studies and I was PhD stipendiate of the Studienstiftung from July 2012 to April 2016. I am alumnus of the Graduiertenkolleg "Cohomological Methods in Geometry" of the DFG (german research foundation) and I am associated to the Graduiertenkolleg "Combinatorial Structures in Geometry" now.

In my free time, I try to learn juggling blindfolded am a parent of three kids (first 2013 then twins 2016). Besides that, I'm a coffee geek and have many project ideas.

If you want a more profound CV, you should contact me directly, although I do offer a (possibly outdated, from November 2016) PDF version of my CV here.

To lighten up your mood, here are some quotes I like:

"Stay hungry, stay foolish." -- Whole Earth Catalog (final issue)

"If you can't solve a problem, then there is an easier problem you can solve: find it." -- George Pólya (in: "How to Solve It")

"It may be that a hundred years from now there will be a programming language that by then has stood the test of time, needs no more changes for most uses, and is used by all persons who write programs because each child learns it in school." -- Guy Steele (in "Growing a Language")

"We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard" -- John F. Kennedy

"The less you do, the more you can do of it." -- Scott Hanselman

"A novice was trying to fix a broken Lisp machine by turning the power off and on. Knight, seeing what the student was doing, spoke sternly: "You cannot fix a machine by just power-cycling it with no understanding of what is going wrong." Knight turned the machine off and on. The machine worked." -- Jargon file

"If you want to build a ship, don't drum up people to collect wood, but rather teach them to long for the endless immensity of the sea." -- (wrongly?) attributed to Antoine de Saint-Exupery

"Don't forget to be awesome!" -- made popular by Hank and John Green

"Work expands so as to fill the time available for its completion." -- Cyril Northcote Parkinson (in The Economist, 1955)
