Research Interests

I am interested in building secure and privacy preserving systems. My current interests include the domains of privacy enhancing technologies, trustworthy social systems, and Internet/network security. My research draws on techniques from computer networks & distributed systems, large scale machine learning, complex networks/network science, and applied cryptography. Please see my publications page for more details.

Select Projects

Privacy Enhancing Technologies
  • Papers: [CCS 2007] [CCS 2008] [CCS 2009] [CCS 2010] [CCS 2011] [USENIX 2011] [TISSEC 2012]
  • We proposed the design of next generation anonymity systems that scale to tens of millions of users, and also found several vulnerabilities in anonymity systems. Our work has influenced the design and threat model of deployed systems such as Tor and I2P.
Trustworthy Social Systems
  • Papers: [NDSS 2009] [NDSS 2012] [IMC 2012] [CoNEXT 2012] [NDSS 2013] [NDSS 2013]
  • We proposed solutions to security and privacy issues in online social networks (OSNs), such as detecting malicious (Sybil) accounts in OSNs and privacy preserving OSN architectures. In recent work, we detected real world Sybil attacks in the Twitter network, and performed the largest measurement study of the Google+ network.

Internet/Network/Web Security
  • Papers: [HotNets 2009] [USENIX 2010] [CoRR 2012] [STC 2012]
  • We proposed defenses against botnets, denial of service attacks, and Sybil attacks. Our work demonstrates the use of large scale machine learning techniques to analyze complex network structures for attack isolation. We applied our techniques to Internet networks, social networks, and even biological gene networks.
