With sorrow, we have to announce the death of Prof. Jerzy Jurkiewicz, who passed away unexpectedly on November 30, 2021. We are mourning the loss of an remarkable scientist, great collaborator, colleague and mentor. Prof. Jurkiewicz was the head of the Theory of Complex Systems Department for many years.

## 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

## Projects

Ongoing:

- Team-Net: Bio-inspired artificial neural networks
- Opus: Studies of the quantum geometry of space-time
- Sonata bis: Compact phase space field theories - from gravity to complex systems
- Sonata: Regulatory mechanisms for reproducible neural pattern specification in the developing spinal cord
- Polish Returns: Principles of information decoding in developmental systems
- Etiuda: New critical region in the Causal Dynamical Triangulations on a torus
