JING MAI

I am a third-year Ph.D. student in the Department of Computer Science at Peking University associated with the Center for Energy-Efficient Computing and Applications (CECA). I am a member of the PKU-IDEA Lab, advised by Prof. Yibo Lin. Previously, I received the B.S. degree in Computer Science and Technology from Peking University in 2021. My research focuses are machine learning-assisted EDA; my broader interests include large language models, MLSys, and robotics.
