I am a Researcher in the Data Management, Exploration, and Mining (DMX) group at Microsoft Research (MSR) in Redmond, WA. I completed my PhD from the Department of Computer Science, University of California Santa Barbara (UCSB) in Fall 2011. I had the pleasure to be advised by Professors Divy Agrawal and Amr El Abbadi during the course of my PhD as a member of the Distributed Systems Lab.
I am originally from the “City of Joy” Kolkata in India. My undergraduate study was in Jadavpur University, Kolkata. I completed my Bachelor of Engineering from the Department of Computer Science and Engineering in 2006.
My broader research interests span the horizon of scalable database management systems. My current research focusses on efficient resource management and automated tuning of multi-tenant relational database-as-a-service. My past research at Microsoft has focused on performance isolation in multi-tenant relational database-as-a-service, and scale-out transaction processing systems leveraging modern hardware paradigms.
My thesis research focused on developing scalable, elastic, and autonomic transaction processing systems to support cloud application platforms. I have worked on projects to design large scale analytics platforms for multi-dimensional data to support location based services and to allow deep statistical analysis over large amounts of data. I have also worked on data management systems leveraging modern hardware paradigms such as flash memory or content addressable memory. In the past, I have also worked on data stream processing systems and wireless networks.
