Kewei Sun has obtained PhD in Physics (Supervisor: Prof. Lifeng Chi) in June 2018 from Soochow University. He then worked in National Institute for Materials Science (NIMS) in Japan as a postdoctoral researcher (Advisor: Prof. Shigeki Kawai) from July 2018. In 2021 he was awarded with JSPS postdoctoral fellowship (Apr 2021 − Sept 2022). He will start working as an ICYS researcher (tenure-track position) in NIMS from October, 2022.Kewei Sun have worked in the field of on-surface chemistry and physics with low-temperature scanning tunneling microscopy/spectroscopy (STM/STS) for more than nine years. The main projects are a) developing various on-surface chemical reactions; b) fabricating carbon-based novel nanomaterials and functional molecules; c) using STM/STS to study the physical and chemical properties of molecules and nanostructures. Thus far, 24 papers have been published in J. Am. Chem. Soc., Angew. Chem. Int. Ed., ACS nano and so on.
