About me

I am currently a first-year CS PhD student at UW-Madison, working with Prof. Shivaram Venkataraman. Before that, I received my bachelor degree from Fudan University in 2023.

During my undergraduate studies, I have worked at System Research Group of Microsoft Research Asia (MSRA), RISE Lab at UC Berkeley, Shanghai Qi Zhi Institute, and Nanyang Technological University. I had industry internships at Moonshot AI and Wish.

Research Interests

My research interests lie in the intersection of machine learning and data-intensive systems.
