01 / A LITTLE CONTEXT

Data is where
capability begins.

I am Meihao Fan (范梅浩), a Ph.D. student in Computer Application Technology at Renmin University of China, advised by Prof. Ju Fan and Prof. Xiaoyong Du. I completed my B.S. at Chongqing Jiaotong University in 2023.

My research focuses on scalable data synthesis for agent training. I develop methods for task generation, interaction-trajectory synthesis, and execution-based data verification, and use the resulting data for curriculum learning and multi-turn reinforcement learning. My work connects data construction to measurable improvements in agent capability and generalization. I am extending this research to embodied data curation, action-conditioned world models, and evaluation-driven data evolution.

I am seeking a Summer 2027 U.S. research internship in embodied AI data, world models, and multimodal agents.
