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, where my thesis characterized zero-waste designs
for networked systems and explored instantiations for auxiliary functions such as monitoring and control.
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 software with emerging hardware for applications; and (2) exploring innovative zero-waste practices for any residual waste.
