# About

I am a PhD student at RWTH Aachen University, Lehrstuhl B für Mathematik, Lehr- und Forschungsgebiet
Algebra in the research group of Alice Niemeyer.

My main interest lie in the intersection between Group Theory and algebraic Graph Theory.

#
#### A Free Blogging Theme
#**Hydejack** started out as a free blogging theme for Jekyll — and continues to be so.
#
#<!--posts-->
#
#
#### An Impressive Portfolio
#A portfolio that's guaranteed to be impressive — no matter what you put into it.
#
#<!--projects-->
#
#
#### A Printable Resume
#Get a resume that's consistent across the board — whether it's on the web, mobile, print, or [PDF](assets/Resume.pdf).

#
#
#### Just Markup
#**Hydejack** boasts a plethora of modern JavaScript, but make no mistake: It's still a plain old *web page* at its core. It works without JavaScript, and you can even view it in a text-based browser like `w3m`:

#
#
#### Syntax Highlighting
#**Hydejack** features syntax highlighting, powered by [Rouge].
#
#```js
#document.getElementsByTagName("hy-push-state")[0].addEventListener("hy-push-state-load", function() {
#  // <your init code>
#});
#```
#
#
### Beautiful Math
#They say math is beautiful — and with **Hydejack**'s [math support][latex] it's also guaranteed to *look* beautiful.
