😎 Hi, I am Junting Lu (Aidan Lew), currently a second-year master student at Institute for Software Engineering, Peking University (PKU). Prior to that, I received the B.S. degree from Northwestern Polytechnical University (NWPU) in 2023.
🌟 I am currently on the job market!
My current research interests primarily focus on:
- Tool Learning: Explore how to endow large models with human-level tool use abilities.
- OS Agent: Develop intelligent agents that utilize (multi-modal) large language models ((M)LLMs) to operate within operating systems (OS) environments.
- Native VLM Agent: Advancing research on equipping MLLMs with hybird Agent abilities.
