Faculty Profile

My research focuses on graph signal processing and trustworthy collaborative intelligence, addressing multi-source 

information sensing and collaborative decision-making in dynamic complex networks. It spans two main areas. 

The first is nonlinear graph signal processing and multi-source spatiotemporal sensing, including nonlinear graph 

filtering, topological signal processing, spatiotemporal sampling and reconstruction, fusion of heterogeneous 

multi-source data, and environmental spatiotemporal field reconstruction. The second is trustworthy distributed 

learning and multi-agent collaboration, including asynchronous federated learning under communication constraints 

and adversarial conditions, interaction topology design, robust collaborative optimization, and security mechanisms. 

I have led projects funded by the National Natural Science Foundation of China, and have participated in projects

 under the National Key Research and Development Program of China.
