Welcome to Jinxiang Meng’s personal homepage.
I am a Master’s student in Computer Science at the University of Chinese Academy of Sciences (UCASNJ), trained at the Institute of Automation, Chinese Academy of Sciences. I am advised by Professor Kang Liu.
My research focuses on building data and environment foundations for reliable general-purpose agents, especially data-intensive and long-horizon agents in real-world workflows. My interests include:
- General agents and data agents
- Long-horizon tasks, model capability optimization, and stable long-horizon training
- Benchmark construction and execution-based evaluation
- Synthetic data, environment synthesis, and post-training
- Structured data reasoning, table reasoning, and Text-to-SQL
Open to opportunities: I am actively seeking 2027 Fall PhD opportunities or full-time job in LLM agents, data agents, long-horizon tasks, synthetic data, environment synthesis, and post-training. Please feel free to reach out if our interests align.
