Personal Information

Jianjun Li got his PhD degree at The University of Hong Kong in 2013. As associate professor, he then worked at Northwestern Polytechnical University, Xi'an, Shaanxi, China, until 2017. During 2015-2017, he stayed at Max-Planck Institute for Iron Research as an Alexander von Humboldt Research Fellow with Prof. Dierk Raabe as his Host. After that he became a Professor at Central South University, Changsha, Hunan, China. He is leading an institute named Mechanics of Micro/nano-structured Materials, which contains 1 professor, 3 associate professors and 10+ master and phd students.

Prof. Li has intensive interests in mechanical behavior of micro-/nanostructured materials by using experiments, modelling and simulation. Prof. Li has published 35+ SCI peer-reviewed journal articles, which have 400+ SCI citations. Most of the articles are published in prestigious journals such as Int. J. Plasticity (5), Acta Mater. (2), Scri Mater (6), IJSS (2), MSEA (6), Appl Phys Lett (1). Prof. Li serve as reviewers for many international journals and the research proposals of National Natural Science Foundation of China.

Our group has been equipped with 1 high vacuum magnetron sputtering with 6 targets, 1 micro hardness tester, 5 computation servers. We are recently focused on the following 3 areas: (1) Microstructure design and fabrication of novel nanostructured metals and alloys; (2) Mechanical behavior of heterogeneous nanostructured metals and alloys; (3) Thermal/mechanical instability of nanostructured metals and alloys. We welcome outstanding students who have strong desires to discover the secrets in nature.
