## About

The **Theory of Complex Systems Department** is a part of the Institute of Theoretical Physics at the Jagiellonian University. It was formed in 2002 by disjoining from the Particle Theory Department
at the Marian Smoluchowski Institute of Physics.

In our research we tacle fundamental physics and interdisciplinary problems, both with analytical and numerical methods.

## Main research areas

- Quantum Gravity and Cosmology
- String Theory and AdS/CFT correspondence
- Random Matrix Theory
- Mathematical methods of theoretical physics applied to interdisciplinary problems
