I graduated from CMU in August, 2015 and recently started as a research scientist at Intel Labs.

My PhD dissertation was on Providing High and Controllable Performance in Multicore Systems Through Shared Resource Management, advised by Prof. Onur Mutlu.

I received my bachelors in Electronics & Communication Engineering from Madras Institute of Technology, India in 2007 and my masters in Electrical & Computer Engineering from Carnegie Mellon in 2012. More about me in my resume.
Research

I work in the broad area of computer architecture.


My specific research interests are in main memory management and providing predictable application performance in the presence of shared resources, in both homogeneous and heterogeneous systems.
Teaching

I enjoyed being a teaching assistant for

Introduction to Computer Architecture,
18-447, Spring 2012 and
Graduate Computer Architecture,
18/15-740, Fall 2010.

I played an active role in different aspects of the courses such as conducting recitations, developing homeworks, exams.

Outside of Work

I enjoy reading non-fiction and fiction. I am also into Indian classical music and enjoy singing and listening.
