Dr Yap Kian Kun specialises in polymer tribology, with a focus on the development of sustainable, self-lubricating, ultralow-wear polymer systems for applications where liquid lubrication is impractical, such as in the aerospace, semiconductor, and food industries. Through self-developed tribometry and in-situ characterisation techniques, he aims to uncover the fundamental interfacial phenomena governing these systems. These techniques include spatiotemporal mapping, high-throughput microscopy, fluorescence microscopy, and surface profilometry. Prospective PhD and Master’s students, postdoctoral researchers, and potential collaborators are welcome to contact him at yapkiankun@sz.tsinghua.edu.cn.
