I’m a 5th year PhD student at the Computer System Lab at the Pennsylvania State University – University Park. My research interests span the areas of computer systems, power/energy management, reliability analytics, and computational sustainability. My advisor is Dr. Anand Sivasubramaniam.

During the summers of 2014, 2015 and 2017, I interned at Microsoft Research, Redmond. My work focused on data center reliability analytics with a special focus on SSD reliability.  I had the opportunity to work with Anirudh Badam, Laura Caulfield, Sriram Govindan, Myeongjae Jeon, Aman Kansal, Bikash Sharma, and Di Wang. I also collaborate with Dr. Hosam Fathy from the School of Mechanical and Nuclear Engineering at Penn State on the energy storage work. Before joining Penn State, I was a Researcher under the guidance of Dr. Arunchandar Vasan and Dr. Venkatesh Sarangan at TCS Innovation Labs – Chennai. We explored the opportunities and challenges in smartening water supply networks using principles from computer science domain.
