I am a senior researcher in the Intelligent
Networked Systems group at Microsoft
Research Redmond (previously Office of the
CTO, Azure for Operators).
I did my Ph.D. in University of Pennsylvania advised by Prof.
Vincent Liu.
Before Penn, I sampled random experiences in various contexts
of networked systems.
My interests are broadly in systems and networking and I am captivated by the tangible, interdisciplinary nature of the domain. I am excited about (1) developing high-efficiency designs that tightly couple emerging hardware, software, and applications, and (2) exploring innovative practices to eliminate residual waste in modern systems. I am also interested in understanding the trade-offs involved, especially in relation to robustness, fairness, and usability.
