Profile

Biography

Jeff obtained his PhD in metallurgical engineering from the University of Queensland in 2013. He continued his research in extractive metallurgy after that as a postdoctoral research fellow, then research fellow for over 5 years.

He has been involved with and managed over 10 research/consulting projects, funded primarily by industry. In all of these projects, he has taken a leading role in providing analytical technique support, especially microscopy and microanalysis, to the research team. During this period, he has accumulated extensive experience in quantitative microanalysis using electron microprobe and laser ablation ICP-MS and applied these techniques in analysing both natural and synthetic materials.

In 2018, he joined the Centre for Advanced Microscopy as a Microprobe Engineer.
