Full CV | Short Resume (November 2009)

My area of research is computer networks with a focus on the inter-domain routing protocols and economics. Using large scale simulation and modeling I'm analyzing how efficient the Internet business models are and what are the possible alternatives. I also seek to understand how emerging technologies, such as network virtualization, can help change the existing Internet business environment.
