Organisational profile

The STO section comprises two chairs:

Probability Theory and Statistics (KS)

The research program Probability studies random spatial structures and its applications in statistical physics and networking, with a focus on random networks, spin systems and self-interacting random processes. The main aim is to identify the scaling behavior for these systems, by applying methodology such as large deviations, combinatorial expansions and coupling techniques.

Stochastic Operations Research (SB)

The research program Stochastic Operations Research focuses on systems that operate in the presence of randomness. It aims at developing mathematical models and methods for the design, analysis, optimization and control of such systems. A large part of the research effort is devoted to queueing theory and the analysis of random walks related to it. Some of the queueing research is of a fundamental nature, and much of it is inspired by problems in production and logistics and in computer-communication systems.
