I am pursuing my PhD in Electrical & Computer Engineering. 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 .

Research

I work in the broad area of computer architecture with my advisor Prof. Onur Mutlu.


My specific research interests are in main memory management and providing predictable application performance in the presence of shared resources.

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 course such as conducting recitations, developing homeworks, exams.
