I am a PhD candidate in the Department of Computer Science at Cornell University advised by Emin Gün Sirer.

My research interests are in building novel, fast, and scalable distributed systems. My current projects focus on distributed event ordering, graph databases, and approximate big data computing.


Research

Event Ordering Services for Distributed Systems
An event ordering service factors the task of tracking happens-before relationships out of distributed system components into a separate service. Kronos is the first fault-tolerant, replicated event ordering service. Our second implementation, refinable timestamps, uses Kronos to enable a highly-scalable, distributed event ordering service.

weaver: A Strictly Serializable Distributed Graph Store
weaver enables high-performance, strictly serializable transactions and graph processing queries on dynamic graph-structured data. weaver uses refinable timestamps to scalably orders graph queries.

ScoDA: Web Content Adaptation for Mobile Browsing
ScoDA is a heuristic web content adaptation technique that is cognizant of both resource contraints on the browsing device as well as viewer preferences. This work was done during an internship at IBM Research.
