My research focuses on security and privacy in widely used computer systems and networks. I have helped detect and evade Internet censorship, measured geographic discimination by content providers, uncovered vulnerabilities in widespread Internet protocols, and worked to prevent HTTPS certificate misissuance. I am also interested in answering questions about practical properties of privacy systems and understanding the concrete improvement in security that different practices achieve.
