Professor of Mathematics and Computer Science
Areas of Expertise: Computer networks, social networks, graph theory, modeling, simulation
I became interested in computers as a child, because I found the mix of creativity and precision required to design programs that control a machine compelling. I studied computer science at MIT, but then decided that I needed to study mathematics to make computers do the things that we as humans, with our incredible brains, do almost effortlessly. In the succeeding years, I have been working to advance the application of computation and mathematics to uncover hidden dynamics in modern societies, from the perspective of flows (information, disease, money, etc.) that circulate in dynamically changing social networks. The work I do involves discrete mathematics, system modeling, data analysis, simulation, and building real computer systems. I like working with students because they are curious and creative about the world, and have the dedication to invest the time and effort to develop the skills needed to be effective as scientists, engineers, and citizens.
