I'm a graduate student in the Parallel and Distributed Operating Systems
group in the Computer Science and Artificial Intelligence Laboratory at
MIT. My advisor is Frans Kaashoek.
I am interested in scaling and security for distributed Internet systems and
networks.
My goal is to develop fully decentralized systems which can potentially scale
to billions of participants. The challenge is maintaining the integrity and
reliability of the system without any centralized authorities and despite
concerted attacks by malicious participants with arbitrary numbers of
pseudonyms.
Research Projects
- Whānau: a scalable distributed hash table secure against powerful
denial of service attacks, including the Sybil attack.
- Eyo: a storage system providing a consistent view of a user's
data (such as photos, music, and email) across her personal devices.
- UIA: naming and routing for personal mobile devices, such as laptops,
phones, cameras, and media players.
- Alpaca: a logic-based proof-carrying authorization framework which enables
extensible cryptographic protocols.
- Barnraising: a P2P content distribution network with untrusted caches.
