About Me

I work for Google in the Madison office. I received my PhD in Computer Sciences, specializing in Database Systems advised by Prof. Jignesh M. Patel in the Database Systems Group of the Department of Computer Sciences at the University of Wisconsin - Madison. My thesis work focused on high performance, relational database system called Quickstep, designed for modern hardware platforms. Quickstep started as a research project in UW under the leadership of Prof. Jignesh M. Patel and was later acquired by Pivotal Inc. (News link). Quickstep is now an Apache (incubating) open-source project.

I worked on all the modules in Quickstep, but my specialization was in resource management, specifically the query scheduler. We designed the Quickstep scheduler to leverage the high degree of parallelism offered by the hardware effectively (utilization) and efficiently (performance) to execute queries.

Before grad school, I graduated from BITS Pilani, India with a Masters in Mathematics and Bachelors in Computer Science. I had a brief stint at Cisco Systems, Bangalore between my two student lives.
