Haoji Zhang (张颢继)

I am a second-year master's student at Shenzhen International Graduate School, Tsinghua University, majoring in Data Science and Information Technology. I expect to graduate in 2027. I am fortunate to be supervised by Prof. Yansong Tang in the IVG@SZ group.

Previously, I received my B.S. in Mathematics and Physics from Tsinghua University in 2024. I have also worked as a research intern in Prof. Jun Zhu's Lab, Prof. Gao Huang's Lab, and ByteDance Seed (working with Dr. Xiaojie Jin and Dr. Jiashi Feng).

My research interests lie in Multimodal Large Language Models (MLLMs), including Efficient Deep Learning and Long Video Understanding. Currently, my work focuses on Agentic Model, Video Spatial and Temporal Grounding.
