I am currently working on a next generation data analytics appliance at Netezza (an IBM company).

Since 2006, I was a graduate student in the UMass Amherst CS Dept. I got my MS in Feb 2009 but continued my PhD work until Feb, 2010. I had to leave graduate school midway for personal reasons. I am still accessible on my email below.

My LA-Tree project won the Outstanding Synthesis Project award in 2009. While at UMass, I worked under the guidance of professors Deepak Ganesan, Yanlei Diao and Arun Venkataramani. I worked on two main research projects: Flash based databases; Transport and Rate-Control for Wireless Networks.

Prior to this, I completed my undergraduate studies for a BTech and MTech in the Computer Science and Engineering lab at the Indian Institute of Technology Madras, Chennai, India.
