Ziniu (Michael) Zhang I am a Ph.D student of Khoury College of Computer Sciences in Northeastern University starting from Fall 2024. I work with Prof. Hongyang R. Zhang. My name can be pronounced as "Tzu-niu Chang". Before my PhD study, I was a visiting student in the University of Queensland advised by Prof. Yadan Luo and a research intern in MMLAB@NTU advised by Prof. Ziwei Liu. I am extremely grateful to all professors, mentors, and friends who have helped me on my research journey. I obtained my bachelor's degree in Computer Science (Honors College) from University of Electronic Science and Technology of China (UESTC) in 2024.
