Jianxi Gao is working in the area of network science, especially on network resilience, robustness, and control. His research is focused on using network theory, control theory, statistic physics, and operation research to understand, predict, and ultimately control the resilience, cascading failures of complex systems. He is also interested in the collective motion of multi agent systems, such as schooling of fish and flocking of birds, which can be applied to distributed sensor networks, unmanned aerial vehicles, and opinion/crowd dynamics on social networks.
