01 / About
In search of truth from chaos.
Dr. Weiqiang Sun is a professor in the School of Integrated Circuits / School of the Information and Electronic Engineering. My work connects network architectures, network and data modeling. I have also contributed to IETF standards for optical network performance measurement, including RFC 6777 and RFC 5814.
I founded SJTU-Health, an online health management platform now serving more than 10,000 members of the SJTU community.
I also created the Agentic Network Planner (ANP), an agentic platform for network planning and design that serves researchers and practitioners around the world.
