The probability and statistics group

Probability theory is the mathematical theory that formalizes randomness. As such, it plays a role in many phenomena of everyday life: spread of epidemics, structure of large networks (biological, computer, social, ...) , thermodynamics, and so on. These models are often motivated by questions in physics, computer science and biology, and provide a fascinating playground for researchers in mathematics. There is also a close and fruitful interplay between probability theory and the other branches of pure and applied mathematics.
