Open positions

The German–Korean International Research Training Group (IRTG) 2235 Searching for the regular in the irregular:
Analysis of singular and random systems
funded by the Deutsche Forschungsgemeinschaft (DFG), currently offers several PhD positions at Bielefeld University.

The IRTG is a joint research program established by the Faculty of Mathematics at Bielefeld University, Germany, and the Department of Mathematical Sciences at Seoul National University, South Korea. In a truly international and competitive environment, doctoral students study singular and random systems.
The IRTG concentrates on advanced techniques from the mathematical field of analysis including geometric, stochastic and numerical analysis together with latest developments in neighboring fields such as mathematical physics and probability theory. The focus is on the mathematical analysis of problems which generically exhibit singular features or randomness. The topics include stochastic dynamics, stochastic partial differential equations, machine learning, nonlinear wave equations, integrodifferential equations, random matrices, generalized Dirichlet forms, analysis on manifolds and fractal metric spaces.

Your tasks

  • Research within a PhD project in one of the research areas of the IRTG
