About

I am currently a PhD student at the Hong Kong University of Science & Technology, under the supervision of Prof. Vincent Lau.

Previously, I earned a BMgmt in Engineering Management from Huazhong Agricultural University, and an MEng in Control Science & Engineering from Huazhong University of Science & Technology, supervised by Prof. Housheng Su. Following this, I worked as an algorithm engineer at FABU.AI, focusing on modeling and solving optimization problems related to autonomous driving. Upon deciding to pursue a PhD, I moved to the Chinese University of Hong Kong, Shenzhen as a research assistant, mentored by Prof. Xiao Li.

For further details, please refer to my CV.

Research Interests

My research interests primarily lie in algorithm design and convergence analysis for decentralized optimization. Currently, I am particularly focused on a class of decentralized optimization problems with globally coupled constraints, formulated as:

minxi∈Rdi,y∈Rp n∑i=1(fi(xi)+gi(xi))+h(y)s.t. n∑i=1Aixi=y,

where fi:Rdi→R is a convex and smooth function, gi:Rdi→R∪{+∞} and h:Rp→R∪{+∞} are convex but possibly nonsmooth functions, and Ai∈Rp×di is a matrix, i=1,⋯,n. In the decentralized setting, we are required to solve (1) over a networked system of n agents, where the network topology is represented by an undirected or directed graph. Notably, fi, gi, and Ai are private to agent i, while h is public for all agents. This formulation captures a broad spectrum of real-world applications, including decentralized control, vertical federated learning, and resource allocation.
