My name is Christoph Lüders. I am a software developer and computer scientist.

I am working for over 25 years for cFos Software GmbH, which I co-founded in 1993. We are building telecommunications and networking software for Windows, including cFosSpeed, an Internet Traffic Shaping driver and cFos Personal Net, a web server.

I graduated from Universität Bonn with a diploma (equivalent to a master’s degree) in computer science under Michael Clausen in 2014.

I am a PhD student under Andreas Weber. I work on tropical geometry and chemical reaction networks as well as machine learning. I plan to finish my dissertation 2019/20.

My research interests are:

- tropical geometry, computational geometry, systems biology and (bio-)chemical reaction networks.
- machine learning, especially neural network driven game play that is self-learned by the machine
- computer algebra and computer arithmetic, especially fast multiplication of extremely large integers (we’re talking billions of digits here) and fast Fourier transforms (since that’s what you use for fast multiplication).

I had a “Stiftungsfonds Johannes Kepler” scholarship in 2015/16.

Privately, I enjoy Salsa dancing (also teaching) and learning Aikido.
