Mathematical Statistics and Data Science

We study mathematical methods and models for analyzing and representing data. Our research combines probability theory and stochastic processes with abstract and linear algebra to understand uncertainty, randomness, and the structure of statistical models.

Teaching

We teach courses in probability and statistics at all levels. Some of the offered courses are eligible as a basis for an SHV degree in insurance mathematics. Doctoral education in probability and statistics is coordinated by the Finnish Doctoral Education Network in Stochastics and Statistics (FDNSS).
