Complex Systems
In this domain, we are dealing with the modelling of interacting systems in networks and between networks. We apply our investigations on several fields such as neuroscience, mobile systems and swarmalators which help to understand the behaviours of systems that move in space according to the decision from the internal dynamics. Several phenomena have been observed from our studies such as synchronization, chimera states, travelling chimera and so on.
