Self Introduction

I'm a final-year undergraduate student at Tianjin University of Commerce, focusing on research in computer vision and large-scale multimodal models.

From Sep 2023 to May 2024, I was a research intern at Megvii Research, supervised by Yuyang Liu

From Apr 2025 to Sep 2025, I was a self-funded visiting student of Mohamed Bin Zayed University of Artificial Intelligence, working with researcher Meng Cao and Professor Xiaodan Liang


Research Experience

Research Intern / Megvii Research(supervised by Yuyang Liu)
Sep 2023 - May 2024

Engineered advanced AI algorithms and advanced applications at Megvii Research.

Contributed to building the AI Service (AIS) infrastructure, enabling mass algorithm deployment via a zero-code, automated productivity platform.


Research Assistant / AI Lab, Research Center for Industries of the Future, Westlake University(supervised by Dr. Yufei Huang)
May 2024 - Sep 2024

Introduced the flexible docking task to jointly predict ligand and pocket sidechain conformations for more realistic induced-fit modeling.

Developed a diffusion-bridge generative model over geometric manifolds with energy-to-geometry mapping inspired by Newton–Euler mechanics.


Visiting Student / Mohamed bin Zayed University of Artificial Intelligence. (supervised by Postdoc Meng Cao)
Apr 2025 - Sep 2025

Proposed COLT, a continual tool-usage framework for video LLMs that leverages a learnable tool codebook to dynamically acquire new tools without catastrophic forgetting.

Constructed VideoToolBench, the first video-centric tool-use instruction-tuning dataset, enabling robust evaluation of tool invocation and lifelong learning.

Achieved state-of-the-art results on MSRVTT-QA (+8.2% accuracy over prior SOTA) and substantial continual learning gains on VideoToolBench.


Awards

* 1st Prize Academic Scholarship, Tianjin University Of Commerce

* M Award in Mathematical Contest in Modeling

* First Prize in Tianjin Region, China Undergraduate Mathematical Contest in Modeling

Social Influence

I have built a strong presence as a dance content creator on TikTok and Kuaishou, with around 200,000 followers and a cumulative 20 million+ views. My engaging and creative dance videos have attracted a wide audience and established me as a recognized dance influencer on both platforms.
