About Me

I’m a graduate student working with Prof. Sam Madden in CSAIL at MIT doing research in high-scaling distributed database systems.

Projects

Here are the (non-confidential) projects in which I’ve been involved. More details when I have time!

• Relational Cloud: database as a service that provides transparent scalability and partitioning that maximizes the locality of co-accessed data. (OLTP/Web benchmarking code here)
• Hedwig: a topic-based publish-subscribe wide-area messaging system designed as a replication service in distributed systems like Yahoo PNUTS.
• H-Store: a distributed main-memory relational database management system for on-line transaction processing workloads.
• Invirt: SIPB’s virtual machine management system. The name of the MIT instance of this service is XVM.
• Corey: an exokernel operating system for many-core architectures.
• WebTables: web-scale information retrieval over structured data.
• Scalable Resilient Overlay Networks: distributed algorithms and systems to enable RONs to scale to thousands of nodes.
• Collaborative Filtering Techniques for the NetFlix Prize: an exploration of low-rank matrix factorization, and of maximum-likelihood estimation of a flexible mixture model using EM.
• CarTel: vehicular sensor network platform that uses open Wi-Fi networks for data delivery opportunistically.
  • Intermittently Connected Embedded Database (ICEDB): adaptive continuous query processing system for environments with intermittent and highly variable network connectivity.
  • CafNet: delay-tolerant carry-and-forward networking stack that enables mobile data muling and provides reliable transport on intermittently connected networks.
• Guarded Atomic Actions for Haskell: a Haskell implementation of the parallelism paradigm known as guarded atomic actions, a form of transactional memory (used in Bluespec System Verilog).
• Data Triage in the TelegraphCQ stream query processing system: an adaptive architecture for load shedding.
• Technology and Infrastructure for Emerging Regions (TIER): communications infrastructure based on delay-tolerant data muling, and spoken and written natural language computer interfaces.
• 802.15.4 Simulation Platform in TinyOS/TOSSIM.
• Recovery-Oriented Computing (ROC).
• Microsoft Search and Microsoft SharePoint Portal Server.
