Hello World

Me on Cerro Santa Lucía in Santiago de Chile. My name is Niklas Rieken from Dortmund, Germany. Until August 2025, I have been a PhD student at the Chair of Management Science at RWTH Aachen University. I submitted my thesis in July 2025 and will defend it this November. My main interests in school and research are combinatorial optimization, in particular matroids, and algorithmic mechanism design. 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.

I am #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.
