Hi there 👋, I am Jie Feng, currently a postdoctoral fellow in Tsinghua University, working in FIB Lab.

• 🌱 You can find my full publication via Google Scholar. Some of my proudest works:
  • UrbanLLaVA[ICCV2025]: a multimodal LLM for urban intelligence with spatial reasoning and understanding.
  • CityGPT[KDD2025]: empowering urban spatial cognition of LLMs through data synthesis and self-weighted tuning.
  • CityBench[KDD2025]: simulation-based evaluation benchmark for evaluating LLMs and VLMs in diverse urban tasks.
  • TrajAgent[NeurIPS2025]: An Agent for Automated Trajectory Modeling via Collaboration of Large and Small Models.
  • AgentMove[NAACL2025]: LLM-based agentic framework for zero-shot human mobility prediction around the world.
  • DeepMove[WWW2018]: a well-known attention-based model for human mobility modeling, cited over 800 times.
• 💬 I’m looking for collaboration opportunities
  • Topics: spatial intelligence, spatiotemporal data mining, large language models, embodied agent, etc.
  • Location: Remote or on-site at Tsinghua University
