Complex Systems and Data Science

As we end the first fifth of the 21st Century, human societies face global challenges of unimaginable scale. Global pandemics pose the risk of killing millions of people and paralyzing economies. Climate change threatens coastal cities, imperils food supply chains, and contributes to the extinction of numerous species around the globe. Unlike many problems facing engineers in the past, the solution to these challenges involves not only the development of new technologies but also an accounting for human decisions and behaviors. For example, while the consequences of climate change pose particular large costs for coastal cities such as Houston, TX, the economic implications for the area of a decline in the importance of fossil fuels would be staggering.

These complex challenges require not reductionist approaches, or optimal technical strategies, but the understanding of the numerous interlocked components and sub-systems that are part of or interact with human societies. Complexity science has for the last 40 year developed a set of approaches and techniques that allows for the exchange of knowledge among the disciplinary silos and for the manipulation of objects without predefined roles or interactions. These include nonlinear dynamics, fractal geometry, statistical physics, network science, and recently, data science.
