Networks are emerging as a common language to model a wide variety of systems in life sciences, engineering, and social sciences. Real-world applications give rise to networks that are unstructured and often comprise of multiple-networks. Furthermore, they support multiple dynamical processes that shape the network over time. Network science refers to the broad discipline that seeks to understand the underlying principles that govern the synthesis, analysis and co-evolution of networks. SIAM Workshop on Network Science seeks to build a community around mathematical and computational aspects of network science. The community will comprise of multi-disciplinary researchers who seek to develop, interact and collaborate on various topics pertaining to network science with an emphasis on rigorous computational and mathematical techniques. It will also promote the training of the next generation of network scientists and applied mathematicians.
