About
I am currently a PhD student at the Hong Kong University of Science & Technology, advised by Prof. Vincent Lau.
Previously, I received a BMgmt in Engineering Management from Huazhong Agricultural University and an MEng in Control Science & Engineering under the supervision of Prof. Housheng Su from Huazhong University of Science & Technology. After earning my MEng, I worked as an algorithm engineer at FABU.AI, engaging in modeling and solving optimization problems related to autonomous driving. Upon deciding to pursue a PhD, I resigned and went to the Chinese University of Hong Kong, Shenzhen as a research assistant, where I worked on accelerated decentralized optimization under the mentorship of Prof. Xiao Li. See my CV for more detailed information.
News
Aug. 2023: I started my PhD at HKUST.
Research Interests
My research interests primarily revolve around the theory and applications of decentralized optimization. Currently, I am particularly interested in developing communication and computation efficient algorithms to solve a class of decentralized optimization problems with globally coupled constraints. In this context, we usually consider a networked system consisting of \(n\) agents, and the underlying network topology can be represented by an undirected or directed graph. The problem of interest can be formulated as follows:
\[ \begin{equation} \begin{aligned} \min_{x_i \in \mathbb{R}^{d_i}, y \in \mathbb{R}^p} \ & \sum_{i=1}^n \left(f_i(x_i) + g_i(x_i)\right) + h(y) \\ \text{s.t.} \ & \sum_{i=1}^{n}A_ix_i = y, \end{aligned} \end{equation} \label{original_pro} \]
where \(f_i:\mathbb{R}^{d_i} \rightarrow \mathbb{R}\), \(g_i:\mathbb{R}^{d_i} \rightarrow \mathbb{R} \cup \{+\infty\}\) and \(A_i \in \mathbb{R}^{p \times d_i}\) are private for agent \(i\), while \(h:\mathbb{R}^p \rightarrow \mathbb{R} \cup \{+\infty\}\) is public for all agents. The problem \(\eqref{original_pro}\) captures a wide range of real-world scientific and engineering problems, including decentralized vertical federated learning, decentralized optimal transport, decentralized resource allocation, and more, which is exactly why it appeals to me so much.
