About Me
I am currently a fifth year graduate student at Princeton University in the Computer Science PhD program and am advised by Michael J. Freedman. I graduated from University of Massachusetts Amherst in 2007 with a B.S. in Computer Science and Mathematics.
I am a member of the S* Network Systems (SNS) group, a subdivision of the Network Systems Group.
I contribute to the SNS Blog where an archive of my posts can be found.
Research
- Dynamic Content Distribution for Virtual Worlds - Developing a scalable, decentralized content distribution network for use in the Meru online virtual world. Meru is being designed as an open, programmable, scalable, secure, and extensible virtual environment which requires a fast, scalable CDN. Virtual worlds present particular scheduling challenges for content retrieval, given both the interactive, real-time nature of users' demands and the amount of potentially-visible content that can exceed users' bandwith capacities.
- Selectively Materializing User Event Feeds - Leveraging Yahoo's PNUTS key-value database system, designed and implemented a framework for efficiently constructing real-time web content that shows the latest events from a user's event feed. Superior performance resulted from a hybrid strategy of selectively materializing each user's feed: events from high-rate producers are retrieved at query time, while events from lower-rate producers are materialized in advance.
- Scalable storage systems - Developing a datacenter-focused storage system—CRAQ (Chain Replication with Apportioned Queries)—capable of good availability, high throughput, and low latency, while providing a sliding scale of read consistency operations (from eventual to strong consistency guarantees). Special consideration is given to high-performance support for cross-data-center replication, using geo-diversity for performance and fault-tolerance reasons.
- Peer-to-peer Content Distribution - Developing a new browser-based peer-to-peer content distribution network called Firecoral. Firecoral enables mutually distrustful users to share their browser caches, yet ensures the authenticity of content and enables users to preserve privacy by expressing flexible content sharing policies.
