Li Jian, born in 1983, is a professor and doctoral advisor at the College of Physics, Jilin University. He received his Ph.D. in 2011 from Peking University's School of Physics and has been teaching and conducting research at Jilin University's College of Physics ever since. From December 2017 to December 2018, he was a visiting scholar at Western Michigan University in the United States. His research mainly involves the development of relativistic density functional theory for atomic nuclei, focusing on its application to explain unusual rotational behaviors, electromagnetic properties, and energy level densities of atomic nuclei. Additionally, he explores the use of machine learning in nuclear structure physics and the effects of nuclear interactions in atomic physics. So far, he has published more than 60 papers in journals like Phys. Lett. B and Phys. Rev. C/A.
