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.

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 (Honor College) from University of Electronic Science and Technology of China (UESTC) in 2024.
