Nikolaus Preisser finished his master's degree in metallurgical engineering in March 2023 and is currently conducting research in the course of his Ph.D. studies. Preisser focused on inclusion metallurgy early on and finished both his bachelor’s and master’s theses in this field. Ongoing research regards the impact of experimental slags containing alkali metal oxides for secondary metallurgy on non-metallic inclusions in steel.

Raymond Longbottom has been a Research Fellow at the University of Wollongong since 2008, where he has worked in diverse areas such as coke and other raw materials, blast furnace and alternate ironmaking, steelmaking, refractories with a focus on improving the sustainability of materials processing. He studied at UNSW, completing his B.Met.E. in 2000, and his Ph.D. in 2005. Previously, he worked at the Norwegian University of Science and Technology (NTNU) as part of the EU-funded Ultra-Low CO2 Steel (ULCOS) project. His interests lie in sustainable iron and steelmaking, in both conventional and alternative processing.
