I am a 5th year PhD student working with Prof. Rajeev Balasubramonian at University of Utah. My research focuses on memory system design for future systems, and improving the performance of big-data frameworks like Hadoop using optimizations across the system stack. After completing my undergrad studies at Delhi College of Engineering (DCE), University of Delhi, I began my graduate career in Fall-2007 working with Prof. John Carter.

I learned a lot while working with some great mentors during my internships. I've worked with John Carter, Karthick Rajamani, and Wei Huang at IBM Austin Research Labs during May-Nov. 2010. I worked with Ashutosh Dhodapkar at SeaMicro Inc. (now AMD) during June-Aug. 2011, and at Violin Memory during Jan.-April 2012. I also interned at FusionIO during Sept.-Dec. 2011, working with Dave Nellans.

In an another life, I worked at the Microwave CAD lab at DCE as a research assistant developing parallel algorithms and simulators for microwave antenna simulations. We developed a parallel algorithm for evaluating Gabor transforms on a distributed-memory parallel machine (a Linux cluster for e.g.). The work was published in WORLDCOMP'07, click here for a local copy.

As an undergrad, I interned at IIT-Kharagpur's Space and Technology Cell, and at Processor Verification Group, ST Microelectronics, Greater Noida. At these places, I worked on numerical models for antenna simulations, and functional verification of VLIW cores, respectively. I also worked on RADIUS protocol based authentication services for heterogeneous user environment at DCE.

I am a vegetarian, and try to be environmentally conscious. I like long bike rides, hiking and Utah's outdoors in general. I am also a Linux enthusiast and interested in how computer science is taught at high-school and university levels. Following is a partial list of things I wrote/compiled while I was an undergrad:
1.A presentation on Linux I gave during a technical symposium at DCE.
2.My short guide to which programming languages should one learn.
3.A very short reading list for general and inspirational reading pertaining to computer science.
4. Some project ideas I never got down to implementing. (1) (2) (3) (4)

My first experiments with the LaTeX many moons ago resulted in the following:
