As a Computer Science Ph.D. candidate at UC Santa Barbara, I design, prototype and evaluate protocols for managing large-scale data in a performance efficient and secure manner. The research topics I am interested in are Large Scale Data Management, Distributed Systems, and Cryptography. Today, much of the data that is produced - including data that is private and sensitive - is stored on third party cloud providers. When the data is outsourced, there exists a fundamental tradeoff between security and efficiency while accessing the outsourced data. My research focuses on designing, prototyping and evaluating protocols that strike a balance between efficiency and security in both trusted and untrusted systems. The increasing popularity of blockchains and the use of third-party cloud -- scenarios in which the servers storing and processing the data are not trusted but the data owners nonetheless need low data access latencies -- makes my research interests highly relevant to today's problems. I am co-advised by Prof.Amr El Abbadi and Prof.Divy Agrawal.
