Dr Soshan Cheong

Research Fellow

Facilities: Electron Microscope Unit, Solid State & Elemental Analysis Unit
Category: Academic Staff

Education

PhD. Chemistry, Victoria University of Wellington, New Zealand

Role

I hold a joint appointment between the Solid State & Elemental Analysis Unit (SSEAU) and the Electron Microscope Unit (EMU). 
My role at the EMU is to conduct collaborative research in the area of advanced transmission electron microscopy (TEM) imaging and spectroscopic analysis, and help managing the JEOL F200 TEM.
At the SSEAU, I develop techniques and protocols for time-of-flight secondary ion mass spectrometry (ToF-SIMS) analysis on biological and organic-based materials, particularly in 2D and 3D imaging.

Interest

Development and application of TEM and X-ray characterisation techniques on functional nanocrystals.
