Hi, I am Chunkang Zhang (张淳慷).

🎓 I obtained my master’s degree from the University of Chinese Academy of Sciences (UCAS), advised by Prof. Le Sun and Prof. Yaojie Lu.

🔬 My research interests include Agentic Memory, Retrieval-Augmented Generation (RAG), Long-Context Comprehension, and Omni modal LLM. I work closely with Jialong Tang and Chulun Zhou at Qwen, Alibaba. I also enjoyed close collaboration with Mo Yu at Hunyuan, Tencent.

💡 I believe that true intelligence requires not just reasoning, but remembering — forming structured, evolving knowledge from raw experience.

📩 If you are interested in my work or potential collaboration, feel free to email me at zkang5051@gmail.com.
