Who I Am

Hello world, my name is Julia. I am a computational biologist and developer at day and a creative mind at night. I love creating responsive web applications, awesome Python apps, and user-friendly interfaces. And my passion is to make it look beautiful in the end.

What I Do

I am working as a PhD student in the group of Prof. Schomburg at the TU Braunschweig. My research focuses on applied systems biology. My Thesis deals with three different projects:

  1. The main project focuses on metabolic modeling and in silico engineering of the thermoacidodophilic archeaon Sulfolobus acidocaldarius, which is of interest for biotechnological research.
  2. I am developing new software for the analysis of these metabolic models, including websites to assist during model creation.
  3. And finally, I am an expert in creating any kind of metabolic maps: the static ones that you can download and print, and the interactive ones, where you can map your data on and do a lot of awesome stuff with.

You can find some examples of my work in my portfolio.

Key skills

  • Object-oriented Python Programming
  • Web Development
  • Database Development
  • Graphic Design
  • Metabolic Modeling & Engineering
  • Systems Biology


PhD student

Department of Biochemistry and Bioinformatics, TU Braunschweig 2016-today

I am currently working on several projects, including metabolic modeling of Sulfolobus acidocaldarius, development of software for metabolic modeling, web development, and big data analysis.

Master of Science in Biology

Technische Universität Braunschweig 2014-2016

I have graduated with excellence in Biology with focus on bioinformatics. I did my Master Thesis at the Department for Bioinformatics and reconstructed the metabolic model of Sulfolobus acidocaldarius. I got the possibility to continue the work on this exciting topic as a PhD student.

Research Assistant

Helmholtz Centre of Infection Research, Braunschweig 2014-2015

I have worked in the lab of Till Strowig from September 2014 to June 2015. I was responsible for mouse phenotyping and DNA assays.

Bachelor of Science in Biology

Universität Bayreuth & Technische Universität Braunschweig 2009-2014

I started my elementary studies of Biology at the University of Bayreuth and finished them in Braunschweig. I finished my Bachelor Thesis at the group of Till Strowig at the Helmholtz Center of Infection Research and focused my studies on the influence of Salmonella infections on the intestinal immune system of mice. During the Thesis, I had my first contact to bioinformatics and wanted to learn more about this exciting topic during my master studies.

#development - projects

Web Development

This website (just as an example).

Python website with Flask

The MMTB is a web page to assist metabolic modelers and biologists with interest in metabolism. The web page has a nice Python backend that communicates with MySQL as database management system. The connection to the frontend is managed by the Flask framework.

Python package for Flux Balance Analysis

Metano is an open-source tool for metabolic modeling. It includes scripts for Flux Balance Analysis, metabolite centric analysis methods and many other tools. I am maintaining the software and enhancing the usability, as well as including new features.

#development - the magic of SVG

I like web development and I love the power and magic of SVG manipulation. And because a picture is worth a thousand words, here are two simple examples:

If you have any questions regarding the examples, e.g. what does those numbers mean? or how do you do this?, just ask me.

#creative stuff

I always need creative hobbies as balance for my analytic work. Thereby, I create logos, web and print content, take tons of photos, and do arts and crafts.


I am a passionate writer with focus on scientific writing and contemporary fantasy.

Balthasar ist ein asozialer Außenseiter mit übermenschlichen Fähigkeiten. Doch als er im Eifer des Gefechts der mysteriösen Emilia das Leben rettet, stellt sie sein Leben völlig auf den Kopf.

Der Feuerteufel

Seit fast hundert Jahren regiert ein verhasster Tyrann über das Land. Dabei hat er es vor allem auf eine spezielle Gruppe Personen mit übermenschlichen Fähigkeiten abgesehen. Bis der achtzehnjährige Sam aufbricht, um sich dem Widerstand anzuschließen und den Kaiser zu stürzen.

In deinem Kopf

Vier Jahre nach der Revolution versuchen erneut böse Mächte, das Land unter ihre Kontrolle zu bringen. Und auch wenn sich die einstigen Freunde in der Zwischenzeit auseinandergelebt haben, sind sie plötzlich alle Teil einer gewaltigen Verschwörung.

Der Teufel steckt im Detail

Janek hat Angst. Er hat Angst vor Menschen, vor Veränderungen und am allermeisten fürchtet er sich vor sich selbst. Seitdem seine Mutter vor vier Jahren auf bestialische Art und Weise ermordet wurde, ist er in seinem ganz persönlichen Albtraum gefangen. Vor allem, weil er ihr Mörder ist.
