Prof. Dr. Pawel Romanczuk
The main research objective of the Romanczuk Group is the development and analysis of individual-based mathematical models of collective behavior. In their research they combine methods from statistical physics, stochastic processes to computational biology, to investigate the following interconnected research questions:
- Do schools, flocks & crowds – from cellular aggregates to animal groups (incl. humans) – share common functional features as a collective information processing system?
- How does collective behavior emerge from sensory inputs? Here, they focus on the question of how individuals integrate visual social information and use it to coordinate their actions.
- How do animal groups perform collective decisions under sensory constraints? Here, the central question is how animal groups are able to perform near-optimal and robust collective decisions despite sensory constraints and highly variable environments.
- What is the interplay between the self-organized structure and dynamics of collective systems and their collectively intelligent (or not so intelligent) behavior?
- Agent-based models
- Stochastic Differential equations / Fokker-Planck equations
- Complex networks
- Numerical simulations und computational analysis of experimental data
