Probability and stochastic analysis

Research areas

The research activities of our group cover the following areas

Stochastic (partial) differential equations 

These equations are used for modelling various dynamical phenomenons (physical, chemical, biological, economic etc.) significantly affected by random effects (random noise). We study equations with random effects, which can be correlated in time (so called fractional noise), with focus on parameter estimation and asymptotic behavior of these models.

OU process

 Stochastic geometry and spatial statistics

This field of probability theory has many applications in image analysis and material science. We focus on spatial and spatio-temporal models of unions of interacting particles.

 Metadynamics and molecular simulations

We study mathematical properties (mainly convergence and its speed) of enhanced sampling techniques for molecular simulations, with focus on techniques based on additional (artificial) potential (such as metadynamics, „flying gaussians“ etc.)

Statistical analysis support

We provide support with statistical analysis and modelling to other cooperating departments. We participated on:

  • Modelling gass permeation through grafen-oxid membranes
  • Quality assessment of the distillation column models
  • Analysis of  exhaust emissions measurement
