Researcher biography
Jeff Chen is a pyrometallurgist with strong expertise in high-temperature phase equilibria and gas/solid reaction kinetics. He has over 15 years of research experience in extractive metallurgy, focusing on metals such as Cu, Pb, Ni, PGM, and Fe, through ongoing research collaborations with major mining and metal producers worldwide. Jeff has successfully secured over 10 million dollars in research funds from the Australian government and industry, primarily through funding schemes like ARC linkage and Trailblazer. His contributions to the field include the publication of over 60 papers in leading journals and major conferences in metallurgy, and he was awarded the Best Paper Award from TMS in 2021.
In addition, Jeff is a recognised expert in various quantitative microanalysis techniques, including electron microprobe (WDS) and laser ablation ICP-MS. His specialization lies in the application of quantitative microanalysis in the field of extractive metallurgy. He played a pioneering role in implementing LA-ICP-MS for trace element analysis in metallurgical materials and has consistently contributed to the development of new standard reference materials for sulfides and alloys. From 2018 to 2021, he served as the state representative for the Australian Capital Territory (ACT) in the Australian Microbeam Analysis Society.
Furthermore, Jeff has been actively involved in university teaching, covering subjects such as chemical thermodynamics, pyrometallurgy, and metal production and recycling
