About

I am a researcher in Computer Architecture at Microsoft Research (MSR). I am also an affiliate associate professor at the Department of Computer Science and Engineering at University of Washington.

My research lies in the intersection of computer architecture, systems, and biology. As traditional semiconductor scaling as started to slow down, I investigate alternative approaches to continue the improvement we have been seeing in computer systems over the last few decades. Approaches I have been studying include hardware accelerators for machine learning, emerging memory technologies, and the use of biotechnology to the benefit of the IT industry. I also work on system software for these new architectures.

Lately, my focus has been on creating an end-to-end system that stores digital data in DNA. I have the privilege to work with a team of brilliant researchers and we have been making quite a lot of progress. Check out our latest announcement.

I received my PhD in Computer Science from University of Illinois at Urbana-Champaign in 2007. During my studies, I’ve collaborated very closely with top-notch researchers at IBM Research, where I also worked on the Blue Gene project. After graduating, I worked for almost 2 years at AMD Research, where I also had amazing colleagues.

ApproxFS

Established: June 2, 2015

File System for Approximate Storage Approximate storage allows tradeoffs between data storage precision and other desirable characteristics such as energy savings, higher performance or higher density. It consists of placing different sets of data in memories or…

Kamino

Established: April 17, 2015

The Kamino project explores ways in which systems should adopt new memory technologies including SSDs (NAND-Flash), battery-backed DRAM and emerging non-volatile memory technologies (phase change memory, memristors, spin-torque transfer memory, etc.) for increased performance and efficiency. The project explores how…

DNA Storage

Established: January 1, 2015

The amount of digital data produced has long been outpacing the amount of storage available. This project enables molecular-level data storage into DNA molecules by leveraging biotechnology advances in synthesizing, manipulating and sequencing DNA to develop archival storage. Microsoft and…
