About Me
I'm a third-year Ph.D. student in Computer Science working in the Systems and Networking Group at University of California San Diego under the supervision of Dr. Amin Vahdat. I earned my Bachelor of Science degree in Electrical Engineering and Computer Science from University of California Berkeley in 2007.
My resume contains more detailed information about me.
Research
My research interests span several systems disciplines. My research focuses on simplifying and automating the development, management and configuration of large-scale distributed systems.
Mace (website)
Making distributed systems easier to build
The goal of Mace is to simplify the development, research and deployment of distributed systems. It consists of an extensible set of APIs geared at modularizing and componentizing parts of distributed systems, a domain-specific C++ language extension describing a system's behavior from which real operating code can be generated, a software engine implementing common distributed system features and functionality, and a model checker capable of finding violations of liveness properties which lead the system to dead states.
My most recent work with Mace involves extending Mace's model checker to run in parallel on large clusters and supercomputers.
Kratos/Corfu
Enabling Strongly-Consistent Cross-Data Center Replication
As applications and infrastructure deployed on a global scale increasingly rely on stateful data center hosted services, these services must be replicated at multiple geographic locations to deliver target levels of availability and performance to all clients. Many of these services require the semantics of strong consistency; however, variations of weak consistency remain the state of the art for wide-area replication. We present a storage service that provides either strong or weak consistency on a per-object basis across a set of wide-area replicas, while meeting performance, availability, and scalability requirements.

Fluxo
A framework for reasoning about and optimizing web services
Fluxo was initially designed as a system that automatically determines good locations for caches in Internet services based on a high-level dataflow model of the service and runtime trace information. Since then, it has been extended to support several more optimizations. Much of this initial work on Fluxo was done while I was an intern at Microsoft Research in Redmond, WA in the summer of 2008.
Past Projects
In the summer of 2007, I interned with the deep web indexing group at Google. My primary responsibility was performing analysis of the deep web crawler's indexing statistics to identify major weaknesses in the existing crawler system.
As an undergraduate at UC Berkeley, I played a small role in the P2 declarative networking project. I also worked on UC Berkeley's then-fledgling undergraduate parallelism initiative; the results of that initiative are be available at Google Code for Educators.
Other Projects
I develop and maintain Boomslang, a package for making common academic graphing tasks less painful.
