I am a senior researcher in the Software HARdware Codesign (SHARC) team at Microsoft
Research Redmond, after spending about a year in the
Intelligent
Networked Systems group (previously Office of the
CTO, Azure for Operators).
I earned my Ph.D. in Computer and Information Science at University of Pennsylvania, advised by Prof.
Vincent Liu.
Prior to Penn, I received an M.Sc. in Electrical Engineering from KTH Royal Institute of Technology and sampled random experiences in various contexts
of networked systems.
My work focuses on (1) developing high-efficiency designs that tightly couple emerging hardware, software, and applications, and (2) exploring innovative aproaches to eliminate residual waste in computing systems. I am also interested in navigating the trade-offs such designs entail, including robustness, security, fairness, and usability. More broadly, I am drawn to the tangible, interdisciplinary nature of the systems and networking domain.
