Haozhe Wang I am a second-year PhD student at the Hong Kong University of Science and Technology (HKUST) (commenced 2024.09), advised by Prof. Fangzhen Lin, and in close collaboration with Prof. Wenhu Chen at the University of Waterloo. I am supported by the Hong Kong PhD Fellowship Scheme (HKPFS). My previous research focuses on reasoning RL, multimodal understanding, and agentic training. My recent focus shifts toward reward-based training and proactive agentic systems for visual generation and video world models. I expect to graduate in 2027 and am actively looking for positions in industry. I have mentored many students for research, feel free to reach out! Feel free to connect! jasper.whz@outlook.com |
