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

Dr Xiaodong Ma obtained his Bachelor's Degree in 2006 and a Master Degree in 2009 from Dalian University of Technology, China, then graduated with a PhD in 2012 from The University of Tokyo, Japan, supported by the Japanese Government (Monbukagakusho: MEXT) Scholarship.

Dr Ma joined The University of Queensland in 2012 right after his PhD graduation starting as a postdoctoral research fellow.

Dr Ma is now the acting group leader of the High-Temperature Processing (HTP) group and leading the HTP Program at JKMRC, SMI of UQ. He is an expert in the experimental and modelling research on thermodynamics and kinetics of high-temperature materials processing for ferrous, non-ferrous and advanced materials. He has extensive hands-on experiences in fundamental study and applied research including solar cell silicon purification, ironmaking, steel secondary refining, copper smelting, metal extraction from low-grade complexed ores, and waste treatment, etc. His research activities also extend to the development of high-strength and high-end specials steels by sophisticated control of second phase particles. Along with the research, he is also good at materials characterization by operating the analytical facilities of SEM, EPMA, TEM, XRD, ICP, etc. He is a pyrometallurgical specialist with a strong interest lying in the decarburization of ironmaking and steelmaking with hydrogen metallurgy and lower CO2 emission technologies in the metallurgical sector.

Dr Evgenii Nekhoroshev is a Postdoctoral Research Fellow at the School of Chemical Engineering and a member of the Pyrometallurgy Innovation Centre led by Prof. Evgueni Jak.

He graduated with a Master in Chemistry (chemical thermodynamics) from Lomonosov's Moscow State University, Deparment of Chemistry in 2012. His Master's Thesis was "Thermodynamic optimization of the NaOH-Al(OH)3-Na2SiO3-H2O system for applications in Bayer's process of bauxite treatment" as part of a bigger project initiated in collaboration with Rusal company aimed at utilisation/valorisation of red mud residues accumulated during the production of aluminium oxide from bauxite ores.

In 2019, he completed a PhD in Metallurgical Engineering at Ecole Polytechnique of Montreal, Canada within The Centre For Research in Computational Thermodynamics (CRCT), where he acquired expertise in FactSage software, multicomponent database development, and was included in the list of official collaborators of FactSage. His PhD thesis was "Thermodynamic optimization of the Na2O-K2O-Al2O3-CaO-MgO-B2O3-SiO2 system" sponsored by Glass Consortium including Corning and SCHOTT glass producers. The purpose of the database he developed was to assist the industry in designing new glasses with special properties: chemically hardened glasses (smartphones), technical glasses with high thermal and chemical resilience (boron-containing glasses), chemically inert glasses, etc.

Short after receiving his PhD, Dr Evgenii Nekhoroshev accepted a position at The University of Queensland as part of the Pyrometallurgy Innovation Centre's team where he has an official title of Theme Leader in Thermodynamic Computations, combining his broad expertise in metallurgy, chemical engineering, applied mathematics, and programming.

Dr Evgenii Nekhoroshev has always been passionate about formalisation and automation of big research tasks. He started working on developing an automated solver for thermodynamic optimisation during his PhD thesis which was improved and finalised using the ideas of Prof. Evgueni Jak about real-time derivative matrix optimization and sensitivity analysis applicable to large multicomponent systems. His contribution to the Centre allowed to make transition to a continuous optimization approach when experimental and modelling streams of work in the Centre are efficiently combined together. It allows to include the most recent experimental datasets into a self-consistent database update with minimal time delays.
