About me

Cheuk-Wai Tai joined Department of Environmental and Materials Chemistry in 2009. His research interests are in the structure-property relationships in funcational materials, electron microscopy applcations and method development. He is also responsible for the transmission electron microscopes and sample preparation equipment in Electron Microscopy Center. In addition, he is serving as an associate editor of the Journal of Electronic Materials and an editor of the Open Engineering.

Previous academic employments:


Awards and Fellowships:
