OTULP

I am currently a Ph.D candidate in HCP Group at Sun Yat-sen University (SYSU), supervised by Prof. Xiaodan Liang. I received my Master's degree at the Sun Yat-sen University (SYSU), supervised by Prof. Xiaobin Chang. Prior to SYSU, I obtained a B.Eng from TYUT and majored in Computer Science and Technology (CS) in 2021.

My research focuses on Multimodal Reasoning, particularly in Understanding and Self-Improvement.

• [2026.02] 🎉 One paper (SemHiTok) is accepted by ICLR 2026.
• [2025.12] 🔥 We release EVA, a framework that internalizes explicit tool calling into the model's intrinsic capabilities.
• [2025.07] 🔥 We release C2-Evo, a method for co-evolving models and data, an agent for drawing auxiliary line.
• [2025.02] 🔥 We release TransMamba, a simple method to quickly adapt Transformer models to the Mamba framework.
• [2023.10] 🎉 One paper is accepted by PRCV 2023.
• [2023.07] 🎉 One paper (DRC) is accepted by ICCV 2023.
