π¨βπ About Me
I am currently focusing on TPMS lattice structure, Mechanical metamaterials and Additive manufacturing, as I pursue my Bachelorβs degree in Mechanical design, manufacture & its automation at the School of Transportation and Logistics Engineering, Wuhan University of Technology.
I have been awarded the Second-class Scholarship twice, in 2022 and 2023, and was hornored as one of the βTop Graduates of the Class of 2024β at my school.
My research journey began with the structural design of Triply period minimal surfaces(TPMS) and additive manufacturing when I was a sophomore. I held the belif that additive manufacturing can significantly shape the development of global economy, as this technique allows for production of architectures with extremely complicated shapes using fewer raw materials.
