Hi there!!👋 I’m Zhiyuan Xu, a PhD student in the School of Computing and Data Science (CDS) at University of Hong Kong (HKU). I am a member of the Super Artificial Intelligence Lab (SAIL), advised by Prof. Hengshuang Zhao. I graduated from the University of Chinese Academy of Sciences (UCAS) in June 2026 with a bachelor’s degree in Computer Science and Technology.

My research interests primarily lie in computer vision-related area, where I’m actively exploring and delving deeper. Currently, I am an intern at ByteDance Seed working on video generation. Before that, I had wondeful research experiences at HKU, UC Berkeley, Tsinghua and CAS.

During my freshman year and sophomore year, I also explored the area of computer networks, by working as a research assistant at Computer Network Information Center, Chinese Academy of Sciences (CNIC, CAS).

Prior to my research journey, I developed a strong interest in competitive programming and computer science during my (junior) high school years. I have participated in various programming contests, such as National Olympiad in Informatics in Provinces (NOIP), International Collegiate Programming Contest (ICPC) and China Collegiate Programming Contest (CCPC).
