Haichao Zhang

I am a third-year Ph.D. candidate in Computer Engineering at Northeastern University, USA, where I am part of the SMILE Lab, fortunate to be advised by Professor Yun Raymond Fu (Member of the Academy of Europe; Fellow of NAI, AAAS, AAAI, IEEE, AIMBE, OSA, SPIE, IAPR, AAIA). My research focuses on generative models, including Visual Language Models, Video Generation, and Trajectory & Motion Synthesis/Prediction. I am particularly interested in bridging these areas to enhance efficient video understanding, AI-driven content creation and autonomous systems.

Prior to my Ph.D., I obtained my M.Sc. degree from Zhejiang University (ZJU). During my graduate studies, I was also a visiting student and remote intern at The Chinese University of Hong Kong (CUHK) and The University of California, San Diego (UCSD) for three months, where I explored various aspects of AI and machine learning research.

Beyond academia, I have industry experience in applied AI research. Most recently, I was an Applied Scientist Intern at Amazon AWS AI Lab, where I worked on video understanding and large language models. Previously, I was a research intern at Tencent (腾讯), focusing on generative models for images and videos.

I am actively seeking a research internship for Fall 2025 and open to collaborations. If you are interested in working together, feel free to reach out!

Some Very Old & Irrelevant Projects

Several years ago, I delved into the fascinating world of sensor modalities and signal processing, sparking a keen interest in embedded platforms. That experience led me to explore further into artificial intelligence and computer vision.
