About Me
I am a mathematician with interest in both theory and technology. I am most excited when transition from one to the other is tangible. Here's a picture of me and a very dreamy lady … but it's way over a decade old:

I enjoy programming, mostly C and Python. I run a tech blag called “nullteilerfrei” together with my friends. Occasionally I make minute contributions to the electronic music compositions of my pal Oli.
Short CV
- (08/17 — today) I am a Security Researcher at CrowdStrike doing malware reverse engineering.
- (04/12 — 07/17) I got my PhD from TU Berlin under supervision of Prof. Dr. Bürgisser. My thesis deals with topics in algebraic complexity theory, representation theory and geometric invariant theory, in particular orbit closure problems.
- (10/05 — 02/12) I studied mathematics at the university of Bonn with a focus on algebraic geometry. My Diplom thesis deals with a certain class of branched coverings and resolution of their singularities.
