About Ronald J. O'Malley

Dr. Ronald J. O’Malley, the F. Kenneth Iverson Endowed Chair of Steelmaking Technologies at Missouri University of Science and Technology, is a leading authority in steelmaking practices and research. Dr. O’Malley is also director of the Kent D. Peaslee Steel Manufacturing Research Center at Missouri S&T, with expertise in process metallurgy, continuous casting, high-temperature thermochemistry, metal-slag-gas systems and reaction kinetics in those systems.

Dr. O'Malley joined the Department of Materials Science and Engineering at Missouri S&T in January, 2014. Prior to that, he worked for 25 years in the steel industry, working for Nucor Steel for 11 years as a Chief Metallurgist and for 14 years as a Principal Research Engineer at Armco / AK Steel. In both roles, he conducted process / product development and research in the areas of carbon and specialty steel production.

Dr. O’Malley earned Bachelor of Science and Master of Science degrees in materials engineering from Drexel University in 1978 and a Ph.D. in metallurgy from the Massachusetts Institute of Technology in 1983. He is currently a member of the Executive Board of the Association for Iron and Steel Technology, serving as AIST's President from 2019-2021. Dr. O’Malley was awarded the AIST's Distinguished Member and Fellow status in 2012, was made an honorary member of AIME in 2021, received AIST Presidential Citations in 2010 and 2013, was the recipient of the AISE Benjiman Fairless award, the ISS Charles Herty Jr award, the Kent D. Peaslee award, and the Richard J. Fruehan award. He is currently a lecturer for several AIST short courses and the Brimacombe continuous casting course, is a mentor for the AIST Foundation Kent D. Peaslee Junior Faculty Award and serves on the selection committee for the Elliott Lectureship Award.

Dr. O’Malley has a broad range of interests that include: steelmaking, continuous casting, solidification & heat transfer, interfacial phenomena, thin slab & strip casting, mold fluxes & slags, steel manufacture, and quality defects & causes.
