PhD Thesis:

• Towards Securing Interdomain Routing in the Internet. Princeton University, September 2009.
  This thesis presents results from the papers "Rationality and Traffic Attraction", "Path-Quality Monitoring in the Presence of Adversaries" and "Protocols and Lower Bounds for Failure Localization in the Internet".
  • The introduction is a less technical overview of the results in these papers, and discusses approaches for tackling problems in network security.    intro only
  • Each chapter provides a more complete exposition of the results in these three papers.    full thesis
  • Slides from my "Final Public Oral" (thesis defense) and job talk.    slides
