About Me
Currently, I am an assistant professor at the Department of Computer and Information Science at the University of Macau. Before this, I am a postdoc research fellow advised by Professors Laura Balzano and Qing Qu at the University of Michigan. I got my Ph.D. degree under the supervision of Professor Anthony Man-Cho So at The Chinese University of Hong Kong and bachelor's degree from Beijing University of Posts and Telecommunications.
Open positions (Fall 2026)
I am actively seeking PhD students with a strong background in mathematics or programming. Research assistants and postdoctoral positions are also available. If you are interested, please feel free to contact me directly! Please visit here for more information!
Research Interests
Broadly speaking, my research interest lies in the intersects of optimization, machine learning, and artificial intelligence. Currently, I am devoted to understanding mathematical foundations of deep learning and generative AI models, including supervised learning models, diffusion models, and large language models. I mainly study how low-complexity structures (e.g., low-rankness, sparsity, over-parameterization) in practical problems lead to favorable optimization properties and use them to mitigate the challenges caused by worst-case scenarios, enable efficient optimization, and improve our understanding of learning phenomena.
Feel free to email me if you are interested in my research. Remote collaboration is also welcome!
