Biography

I am a PhD candidate at the University of Hong Kong and an intern at Ant Group. Before that, I was an algorithm engineer at Alibaba DAMO Academy. I received the B.E. and M.S.E. degrees at Dalian University of Technology (DLUT), China. My research interests encompass a diverse range of topics within the field of medical artificial intelligence, with a focus on registration, segmentation, time series intelligence, and vision-language pre-training & multimodal learning.
