Longbottom, Raymond J.

Overview

Dr. Raymond Longbottom has been a Research Fellow at the University of Wollongong since 2008 and within the Steel Research Hub since 2015. He studied at UNSW and completed his B.Met.E. in 2000, and his PhD in 2005. Before coming to UOW, 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. Dr Raymond Longbottom has 16 years’ experience in iron and steelmaking research.
