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 trust-

worthy 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. I serve on the editorial boards of JNaNA and as a Technical Program Committee member 

for international conferences, including IEEE ICC and IEEE GLOBECOM.
