Biography: Professor Lin Li is Director of Laser Processing Research Centre at The University of Manchester, UK. He served as President of Laser Institute of America (2016), President of International Academy of Photonics and Laser Engineering (2013–2015), and President of Association of Industrial Laser Users (AILU–2017–2019).

He is an elected Fellow of Royal Academy of Engineering (FREng), Fellow of Laser Institute of America (LIA), Fellow of International Academy of Production Engineering (CIRP), Fellow of International Academy of Photonics and Laser Engineering (IAPLE), and Fellow of Institute of Engineering and Technology (IET). He is an author and co-author of over 400 publications in peer-reviewed journals related to laser-based manufacturing and an inventor or co-inventor of more than 60 patents. He received Sir Frank Whittle Medal from the Royal Academy of Engineering in 2013 for innovative manufacturing that has generated significant economic impacts. In 2014 he received Wolfson Research Merit Award from the Royal Society for his research on laser nano-fabrication and nano-imaging and received the Researcher of the Year medal from The University of Manchester in 2014. He received the Arthur Schawlow award from Laser Institute of America in 2019 for distinguished achievements in laser-based manufacturing, and the Donald Julius Groen Prize, and the Arthur Charles Main Award from the Institution of Mechanical Engineers for leadership in additive manufacturing.

He obtained a BSc degree in Control Engineering from Dalian University of Technology (China) in 1982 and a Ph.D. degree in Laser Engineering from Imperial College London in 1989. He worked at The University of Liverpool (UK) between 1988 and 1994 as a Research Associate and Research Fellow in laser material processing and became a Lecturer in Manufacturing at The University of Manchester Institute of Science and Technology (UMIST), UK, and was promoted to a Full Professor in Laser Engineering in 2000. He served as the Deputy Head of School of Mechanical, Aerospace and Civil Engineering at The University of Manchester during 2009–2013 and served as the Associate Dean of Faculty of Science and Engineering at The University of Manchester during 2015–2020.

Hui Wang is the Deputy Director of the Office of International Cooperation in the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences (CAS). She currently works on international communication and cooperation for the CIOMP and was a founding member for the Nature Publishing Group and CIOMP joint journal Light: Science and Applications. She is the founder of “Rose in Science” and has published several articles in Acta Editologica, International Talent, Light: Science and Applications, etc., and was invited to take an interview by SPIE Women in Optics, which was published in 2015.

Heng Gu is a qualified professor in the School of Mechanical Engineering, Jiangsu University. He graduated from The University of Manchester, UK, in 2018, under the supervision of Professor Lin Li. Heng held a postdoctoral position in the ASTUTE project team funded by the European Regional Development Fund at Cardiff University, UK, from 2018 to 2020. He worked with local Welsh companies (including Airbus, Continental, etc.) on a range of projects. His research interests focus on laser material processing such as laser metal deposition, laser welding, and multi-material additive manufacturing. He has published more than 10 papers in journals including the International Journal of Heat and Mass Transfer, Additive Manufacturing, Optics and Laser Technology, and has served as a reviewer for several international journals.
