About me

Daocheng Fu is a Ph.D. candidate at Fudan University’s College of Computer Science and Artificial Intelligence, in a joint training program with Shanghai AI Laboratory. He is advised by Prof. Yu Qiao and Dr. Botian Shi, and his research focuses on data synthesis, language model reasoning and continual learning.

News

• [2025-09-30] RE-Searcher investigates the relationship between search agents and the search environment, proposing a solution to enhance the agent’s stability.
• [2025-08-30] We release the GeoTrust-train & GeoTrust-test dataset at huggingface.
• [2025-08-29] TrustGeoGen is a data engine for multimodal geometric reasoning, built upon a formal engine, designed to synthesize challenging, full-modality, and trustworthy geometric reasoning data. The introduction of Connection Thinking and Thinking Template enhances the geometric reasoning capabilities of Large Multimodal Models (LMMs) without compromising their general abilities.
