My research lies at the intersection of information security, distributed systems, and computer networks. The overarching goal of my work is creating and building robust distributed systems and network protocols that achieve their security, availability, and performance design goals in spite of misconfigurations, failures, and attacks. My research combines theoretical principles and experimental methodologies from distributed systems, cryptography, networking, information theory, and machine learning to create systems and protocols based on provable guarantees and validated in realistic network environments.

My research has been funded by the Center for Education and Research in Information Security and Assurance (CERIAS), by the Defense Advanced Research Projects Agency (DARPA), and by the National Science Foundation (NSF) .

Current Projects

  • Theoretical and empirical analysis of secure communication protocols.
  • Security and resilience of software defined networking (SDN).
  • Automated testing and verification for distributed systems.
  • Automated text interpretation with application to security and privacy.
  • Data analytics to improve fault-tolerance and security.
  • Adversarial machine learning.

Past Projects

  • Insider-resilient protocols using diversity.
  • Secure networks using network coding.
  • Trusted overlay networks.
  • Byzantine resilient routing for wireless networks.
  • Practical Byzantine-resilient replication services.
  • Secure group communication
