Modeling Complex Systems – from Cell Swarms to Social Dynamics

This page presents my key research areas, selected projects, and publications.

About

I develop mathematical and computational models of collective behavior in social and biological systems. My work draws on statistical physics, network theory, and AI-based simulation to explore emergent phenomena such as hierarchy formation, opinion polarization, group intelligence, and adaptive self-organization. Applications range from smart city dynamics and immune response modeling to outlier detection and behavior prediction.
