Research interest:

Understanding and modelling social (and biological) systems using tools and methods
borrowed from the fields of physics and information technology.
This is very close to the rapidly emerging scientific field called Computational Social Science.

I am particularly interested in belief systems (in its wider sense): how beliefs are organized in humans (and what beliefs are, in a deeper sense), how this system can be represented mathematically, how it effects the dynamics of opinions and how can our understanding of human belief systems utilized in artificial systems.

I am also intersted (and worked quite a bit) on the characteristics of optimal self-organizing groups, especially from the viewpoint of optimal collective decision making.
