Biogeraphy
Currently, I am an associate professor at the PALM Group, School of Computer Science and Engineering, Southeast University.
I received my B.Sc. degree from University of Science and Technology of China, M.Sc. degree from University of Chinese Academy of Sciences, and Ph.D. degree (supervisor Prof. Xin Geng) from Southeast University.
Research Interests
My research interests include deep learning and data mining. Furthermore, I focus on the training and application of Large Language Model (LLM). As the Principal Investigator of the national innovation center in the EDA field, I have leveraged the center's large-scale GPU cluster to build the first LLM specifically designed for the chip design domain, ChatICD-ChipExpert.
