About Me
I am currently a postdoc research fellow advised by Professors Laura Balzano and Qing Qu at University of Michigan. Before that, I got my Ph.D. degree in Systems Engineering and Engineering Management advised by Professor Anthony Man-Cho So at The Chinese University of Hong Kong.
Research Interests
My research interests mainly lie in non-convex optimization for low-complexity representation learning and their applications in machine learning, signal processing, and data science, such as subspace recovery, community detection, constriained PCA, and neural collapse. Currently, I am devoted to understanding mathematical insights into deep learning via low-complexity modeling and non-convex optimization.
Feel free to email me if you are interested in my research. Remote collaboration is also welcome!
