# Hi!
- * I'm Christopher Gadzinski, a student of pure mathematics.
- * I'm currently doing a Ph.D. at the University of Luxembourg in a hybrid of mathematics and applied machine learning. My advisor is Decebal Mocanu.
- * I live for clear understanding. I love returning to something I've seen before and thinking about it from a new perspective.
- * Feel free to contact me by email. Username is me, host is cgad.ski.
- * I'm also active on [mathstodon](https://mathstodon.xyz/@cgadski) and physically reachable at the 3rd floor of the Maison du Nombre here in Belval, Luxembourg.
- * CV / resume is available [here](/resume.pdf).

This document is a sort of [quine](https://everything2.com/?node=quine). If you select the whole page in your browser and paste it into a file, this text shows up encoded in a weird [Markdown](https://en.wikipedia.org/wiki/Markdown) variant embedded in a string literal inside a [Racket lisp](https://racket-lang.org/) script. Evaluating the file with `racket -f $FILE`
evaluates the lisp, converting the weird Markdown and producing the same HTML document that your browser received.
