Pietro Battiston, an economist at Sant’Anna School of Advanced Studies, Italy, is Barnard’s 2017 Weiss International Visiting Scholar.
Originally known as "graph theory", and considered an abstract sub-discipline of Mathematics, in the last couple of decades the theory of networks has made its way into the social sciences. It is now used to understand an ever growing number of topics, such as trade flows, finance, epidemics – and obviously social networking sites! The recent availability of data and methods helps explain this growth; but as Dr. Battiston will show, networks nowadays are studied more also because the world we live in is becoming more interconnected.
Battiston, who bases most of his studies on network data and methods, will present some examples of “global networks,” and guide the audience through the fundamental concepts of this discipline, showing how these new insights are helping policy makers and entrepreneurs make important decisions. This talk is intended for a general audience. Anyone interested in learning about social networks is encouraged to attend.
