Networks with similar properties emerge in an incredible variety of domains — from technological networks like the web to online social networks in human biology. Jennifer T. Chayes, Distinguished Scientist and Managing Director of Microsoft Research New England and New York City, will explore the mathematics that unifies many of these networks, and the often surprising conclusions that can be drawn from such mathematics. Jennifer will be introduced by Henry Cohn, principal researcher at Microsoft Research New England and adjunct professor of mathematics at MIT.
