As the project leader or principal investigator, I have undertaken one National Key Research and Development Program project, one National Natural Science Foundation project, two National Development and Reform Commission CNGI projects, one Guangxi Key Research and Development Program project, and multiple projects commissioned by ministries and commissions. I am the co-leader of the National Key Research and Development Program Major Project "Key Technologies and Demonstration of Internet of Things and Smart Cities," the principal investigator of the Zhongguancun Laboratory 251 project, and a core member involved in multiple projects, including the National 863 Program and the National Science and Technology Support Program. I have led the development of the first multicast video conferencing system in China and implemented the world's first deployment and application of a wide-area Native multicast network environment. I have also presided over the development of a smart city digital twin platform that supports the integration of IoT/video and intelligent computing. I have published over 40 academic papers in domestic and international journals and at international conferences as the first author or corresponding author, and participated in the formulation of three national standards.

National Standard:

[1] National Standard "Smart City—Guide for Application of Sensing Terminals" GB/Z 42760-2023, Standard Drafter
[2] National Standard "Smart City—Guide for Classification of Application Scenarios of Artificial Intelligence Technology" GB/Z 42759-2023, Standard Drafter
[3] National Standard "Smart City—Reference Architecture for Urban Intelligent Hub" GB/T 45402-2025, Standard Drafter
[4] Group Standard "Technical Requirements for Data Interface of IoT Devices in Smart Communities," Standard Leader
