Jun Li is Professor of Chemistry at the School of Chemistry and Chemical Engineering, Chongqing University, PR China. He received his Bachelor and Doctoral degrees from Sichuan University. He worked with Professor Sheng-Hsien Lin as a visiting student at National Chiao-Tung University, PR China on photochemistry for five months. After a three-year postdoctoral research role with Prof. Hua Guo at University of New Mexico, USA, he joined Chongqing University as an independent PI. With a Humboldt Fellowship for Experienced Researchers, he then worked with Professor Jörg Behler at Georg-August-Universität Göttingen, Germany. He has published more than 120 peer-reviewed articles and 2 book chapters “Data Quality, Data Sampling and Data Fitting: A Tutorial Guide for Constructing Full-dimensional Accurate Potential Energy Surfaces (PESs) of Small Molecular Systems” by Jun Li*, Yang Liu, in the book entitled Machine Learning in Molecular Sciences (Springer Nature, 2023) and “Tunneling in unimolecular and bimolecular reactions” by Hua Guo, Jianyi Ma, and Jun Li in Molecular Quantum Dynamics: From Theory to Applications (Physical Chemistry in Action), Edited by Fabien Gatti, Springer 2014. His research interests include potential energy surfaces, reaction kinetics, dynamics, and atomic-level mechanisms, mainly for gas phase systems, and machine learning.
