The Department of Mathematical Modeling was established in 2005.

The head of the department from the beginning its existences is  prof. Piotr Matus (

The Department conducts both research and teaching activities.

Our research focuses on mathematical modeling. Mathematical modeling consists of creating a mathematical model representing the initial object and further analysis of the model created by utilizing computational and numerical methods. The results are obtained by following the steps: modeling - creating algorithm – coding, discussion of the numerical results. For every researcher modeling constitutes a universal tool applicable in variety of fields like mathematics, physics, medicine, biotechnology and others.
