Hello World

Me on Cerro Santa Lucía in Santiago de Chile. My name is Niklas Rieken and I am a computer scientist from Dortmund, Germany. I am currently #opentowork. If you are interested in a person that solves mathematical optimization problems for you, I would be glad to hear from you over your preferred channel.

I studied computer science at RWTH Aachen University and obtained my master’s degree in 2019. In 2025, I also obtained my doctorate degree in economics after being a PhD student at the Chair of Management Science. My field of research was combinatorial optimization, in particular matroids, in the broader context of auction theory. However, as a computer science graduate, I also like formal language theory, logic, and automata theory.

Apart from that I am sports enthusiast, especially football (American and European), baseball, ultimate frisbee, table tennis, and chess. I also enjoy listening to and playing (guitar and ukulele) music and watching movies.
