Hi, I'm currently a 3rd year PhD student in the College of Computer Science and Technology at Zhejiang University (ZJU), and expected to get the PhD degree in 2028. I'm co-advised by Prof. Wei Dong (董玮) and Prof. Yi Gao (高艺). Prior to that, I received my B.E. degree from the School of Computer Science and Engineering at Southeast University (SEU), Nanjing, in 2023, advised by Prof. Fang Dong (东方).
