About me

I am a PhD candidate at Nanyang Technological University (NTU), supervised by Wei Yang Bryan Lim and Chunyan Miao. My research focuses on collaborative AI and model merging.

I am affiliated with the Alibaba–NTU Global e-Sustainability CorpLab (ANGEL). Previously, I was affiliated with the Joint NTU–WeBank Research Centre on Fintech. I received my BSc in Mathematics and Applied Mathematics from The Chinese University of Hong Kong, Shenzhen, in 2023.
