Personal profile

Dr. Keqin (Kevin) Liu (刘克勤) received his Ph.D. degree from the University of California at Davis in 2010 and joined the industry as a software engineer in 2012 after 2 years of postdoc experience. After 8 years of working in the Silicon Valley, Dr. Liu still has a lot passion in mathematics and decided to return to the academy in 2020 when working in ASML and subsequently taught in Nanjing University until joining XJTLU in 2024.

Research interests

Dr. Liu’s research interests include the development of modern math theory for AI technologies, the extension of pure math theory, especially number theory, and the application of pure math theory to solving practical problems in machine learning, e.g., multi-armed bandit in reinforcement learning.
