My research delivered 45 publications in reputed international journals, peer-reviewed conferences and book chapters (citation: 286, h-index: 10). My work of multi-scale tooling manufacturing using BMGs was published in Materials Today in 2012 and was highlighted by Elsevier, Physics News, and Science Daily with the article of “Making Microscopic Machines Using Metallic Glass”. The subsequent work on this topic published in the Journal of Micromechanics and Microengineering was chosen as “IOP Select”. My work on the relationship among material-processing-morphology-properties of miniaturized microinjection moulded products was featured by Society of Plastic Engineers in 2015 and subsequently published in German industry magazines and journals. I also actively developed some new manufacturing processes for hard and brittle materials, multi-scale tools, and high precision polymeric optics, which are reflected by submitted innovation disclosure forms or patents.
