Sven Jäger
I am a permanent research assistant associated to the DISCO Group at TU Berlin. My tasks comprise teaching (in particular Computerorientierte Mathematik), research, and administrative tasks such as organizing the Dies Mathematicus and contributing to the design of study programmes. My research is mainly concerned with approximation and online algorithms, in particular for scheduling problems, as well as game-theoretic methods in public transport applications.
Between 2016 and 2021, I did my PhD in the COGA Group at TU Berlin under the supervision of Martin Skutella. Afterwards, I worked one year in the Optimization Division of the Fraunhofer Institute for Industrial Mathematics and 2.5 years as a postdoc in the Optimization Research Group of the RPTU in Kaiserslautern.
