Research Interests

The objective of our research is to elucidate the emergen behavior of complex systems in terms of mathematical physics, as well as considering real applications of the emergent systems. We are especially interested in the interdisciplinary study of collective dynamics of self-driven particles and its jamming phenomena, which we call jamology, including vehicles, pedestrians, ants, packets in logistics and internet, proteins in organisms. The jamming phenomena in this study is considered as a kind of dynamical phase transition from free to congested state due to instability of flow. Our research is based on mathematical and physical analysis, followed by computer simulations and experiments in order to create better models that show emergent properties. The research subjects include reduction of traffic jam on highway, smooth evacuation of pedestrians, social animals and their emergent behaviors, supply chain network and granular flow.
