Huazhong University of Science and Technology

I am currently a Postdoctoral Research Fellow at National Key Laboratory of IoTSC, Univesity of Macau. Before that, I was a postdoctoral researcher in the School of Computer Science and Technology at Huazhong University of Science and Technology (HUST), Wuhan, China, from 2023 to 2026. I received my B.S. degree from Dalian Maritime University in Jun. 2018 and my Ph.D. degree from HUST in Jun. 2023, under the supervision of Prof. Hai Jin. My research interests mainly focus on edge inference optimization, including optimizing RAG and KV-cache mechanism for resource-limited edge environments.

(I am looking for highly motivated undergraduate students with a strong passion for working with me. If interested, please drop me a message by email.)
