Research Interests

I am interested in censorship circumvention and censorship-resistant publishing with an emphasis on the implementation and real-world deployment of reliable and secure systems. I am also interested in formal methods and software engineering.

Current Projects

I have several ongoing research projects:

Slitheen: A Decoy Routing System for Censorship Circumvention

Slitheen is our new proposal for a decoy routing system. Decoy routing allows users to circumvent censorship by communicating with routers on the path between a user in a censored region and an unblocked website outside of the censor's area of influence. The user indicates to a router with a deployed relay station that they wish to access a censored website, and the router delivers content from that site to the user while maintaining the illusion to a censor that the user is browsing the unblocked site.

Censorship-Resistant Publishing

Censorship-resistant publishing systems allow users to publish content in a safe environment where it will not be attributed to them or deleted by a censor. Existing tools are designed to protect and enable journalists to export data out of a censored region, or require participants to own and maintain large servers in a P2P system. Many users lack the domain knowledge to publish content in this manner. We aim to design a system that gives users both the agency and the protections necessary to participate actively in censorship resistance, allowing them to report on events or produce content contrary to a censoring authority, and share it in a safe and anonymous manner.
