Graduate Student, University of Michigan
Computer Architecture, Operating Systems
I am a final year PhD candidate in CSE, studying computer architecture and opertaing systems at University of Michigan, Ann Arbor. I work with Prof. Tom Wenisch. I got my Masters in CSE from University of Michigan in 2013 and my Bachelors (B.Tech Honors) in Electrical Engineering from the Indian Institute of Technology, Bombay (IITB), India in 2011.
In my thesis, I have primarily focussed on heterogeneous memory management at both hardware and operating systems abstraction level. Heterogeneity is a common feature of computer systems ranging from smartphones, data-centers to supercomputers, composed of different memory technologies and processor types. Main memory technology contributes to significant cost of the overall system cost. Hence, making decisions about memory management in such heterogeneous eco-system is critical to maximizing performance per dollar. Heterogeneous memory systems pose multi-fold challenges on decisions about data placement and movement that have to be made at application runtime – preferably in an application-transparent manner – while considering difference in bandwidths, latencies, and costs-per-bit of different memory technologies.
In my research I tackle memory management of two categories of heterogeneous systems: a) CPU-GPU systems with a unified virtual address space, b) Cloud computing platforms that will deploy cheaper but slower memory technologies along with DRAMs to increase perf/dollar. My research shows that it is possible to improve programmability and save overall system cost while performing close to optimal.

I am an avid traveller. I have been to 86 cities across 16 countries :). Listing countries continent wise: Asia: India, Japan; Africa: Egypt, Morocco; Europe: Turkey, Switzerland, Germany, France, Italy, Vatican, Netherlands, Belgium, Spain, and United Kingdom; North America: United States and Mexico. Thus, continent count is 4 so far, 3 more to come! I have also covered 50% of the states in India! I am thankful to have born in a country with so many diversities in various aspects of life!
I love to try out living in new places. Since, childhood I have lived in 8 cities. In India, I have lived in Allahabad, Jaipur, Jabalpur and Bombay. Outside India, I have lived in Lausanne-Switzerland; Cambridge-United kingdom; Ann Arbor, Austin, and Palo Alto-United States. Thanks to my parents for making me adaptable to new living conditions since childhood!
