**Jie Yin**

Prof. Dr. Jie Yin is currently a Professor and Doctoral Supervisor at the Gemological Institute and Advanced Manufacturing Research Center of China University of Geosciences (CUG). He received his Ph.D. degrees from Huazhong University of Science and Technology (HUST) in 2014, then he joined in Wuhan National Laboratory for Optoelectronics (WNLO) as a post-doctoral and associate researcher for six years. His research focuses on laser advanced manufacturing and laser-matter interaction. He is the recipient of the Young Outstanding Talents of CUG Scholars; of the Best Paper Award from the International Conference on Research Advances in Additive Manufacturing (RAAM 2019); and of the Excellent Report Award by the 4D Printing Technology Forum in 2022. He has leaded more than 10 projects including National Natural Science Foundation of China (NSFC), Shanghai Aerospace Science and Technology Innovation Key Fund (SAST), and the Fundamental Research Funds for the Central Universities. He has served as Editorial Board Member of international academic journals such as Micromachines, and reviewers for 20 academic journals. Furthermore, he has published more than 40 academic papers on International Journals (five representative papers with a total IF=55.5 in the past 5 years), with more than 2400 citations in Google Scholar, 3 ESI/F5000 highly cited papers and two cover papers.

#### **Yang Liu**

Prof. Dr. Yang Liu is currently an associate professor in the Department of Mechanical Engineering of Ningbo University. He received his PhD degree from South China University of Technology in 2015, and he worked as a visiting scholar in Cardiff University from 2018 to 2019. Prof. Liu is the head of the additive manufacturing research group in NBU, and one of the early scholars to study the properties of additive manufacturing alloys such as Ti, Al, and HEAs under extreme work environments (high pressure, high velocity or high/low temperatures). His work mainly aims to reveal the dynamic deformation behaviors and failure mechanisms of additive manufacturing alloys under dynamic loading, which is helpful to widen the application of additive manufacturing techniques and products. So far, he published more than 25 journal papers as first/corresponding author with more than 1400 citations, and undertaken more than 10 research projects.
