case study: Dynamics of routes using traceroute

explanations on


My Ph.D is centered on the study of evolving networks. I work in particular on internet topology, peer-to-peer exchanges and social networks.

I'm also interested in Exploratory Data Analysis applied to graph visualization and interaction. I like to discuss with sociologists and designers as well.
