The emerging field of network science focuses on studying complex systems and how they are all alike. Understanding one network may shed light on other networks. Scientists from a variety of different disciplines have gone deeper into researching complex systems. SFI External Professor and physicist Mark Newman started working in the field ten years ago with SFI and the Center for the Study of Complex Systems. Network science has opened the door to interdisciplinary training in complex systems. Many researchers take these courses through SFI, a leader in interdisciplinary studies and complex network science. Many agencies, including the US National Institutes of Health, the National Science Foundation, and even the military have made donations and funding available to continue research into network science and complex systems.
