  • Stochastic models of popularity on networks
    We are developing models for the diffusion of information (“memes”) or choices among multiple items, in the context of online social networks such as Facebook and Twitter.

  • Complex networks: models of structure and dynamics
    We have developed methods for analytically calculating the expected size of cascades on random networks, and on networks with clustering (transitivity) and modular structures. Recently we extended these methods to a general class of binary-state dynamics. We have also investigated why mean-field theory often works well, even on highly-clustered networks, and we are interested in generalizing results to multiplex networks.
