Introduction

Dr. Liu received his Bachelor degree in 2010 and Ph.D. in 2016, both from Nanjing University of Aeronautics and Astronautics, China. His Ph.D. thesis was elected as the excellent doctor degree dissertation of Chinese society of theoretical and applied Mechanics in 2017. He is now an associate professor at Nanjing University of Aeronautics and Astronautics and supported by ‘the program of Changkong Scholar’. His main research focuses on applying density functional theory to study the micro- and nano-mechanics and developing new semi-empirical methods for van der Waals interaction. He has co-authored over 20 peer reviewed papers, including Nature Nanotechnology, Nature Comminutions, Physical Review Letters, ACS nano, Small, Physical Review B and etc. These papers have received over 1100 citations (google scholar data). He has been supported by the National Natural Science Foundation of China (both the youth project and general project).
