Jie Feng is currently a postdoctoral researcher in the Department of Electronic Engineering at Tsinghua University. From 2021 to 2023, he worked at Meituan as a researcher specializing in intelligent decision-making and large language models. He received his B.S. and Ph.D. degrees (advised by Prof. Yong Li) in electronic engineering from Tsinghua University in 2016 and 2021, respectively. His research mainly focuses on large language models, spatiotemporal data mining and urban science, with over 40 papers published in top-tier venues including KDD, WWW, UbiComp, NAACL, AAAI, TKDE, etc. His work has garnered more than 3000 citations on Google Scholar. His research is supported by the Shuimu Tsinghua Scholar Program and the China Postdoctoral Talent Plan.

We are seeking self-motivated interns and collaborators to conduct research on spatio-temporal data mining, large language models, embodied agent, etc., with us remotely or at Tsinghua. Our interns have good record of publishing first-author papers in CCF-A conferences/journals. Feel free to contact me via email if you are interested.

Research Interests

• Large Language Models: investigating techniques for building domain-specific, multi-modal LLMs for urban systems, e.g., CityGPT and CityBench.
• LLM based Agents: building powerfull intelligent agents for urban applications, e.g., AgentMove, TrajAgent and LMP.
• Spatiotemporal Data Mining: trajectory mining, traffic forecasting, e.g., UniST.
• Urban Science: human dynamics, urban dynamics, in-depth and data-driven analyses of urban issues.
