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 especially excited about minimizing waste in networked systems by (1) developing high-efficiency designs that tightly couple emerging hardware, software, and applications, and (2) exploring innovative practices to eliminate residual waste. I am also interested in understanding the trade-offs involved, especially in relation to robustness, fairness, and usability.
