Hong Yong Sohn received his Ph.D. in Chemical Engineering in 1970 from the University of California - Berkeley.  After working as a Research Engineer at Du Pont’s Engineering Technology Laboratory, he joined the faculty of the University of Utah in 1974.  Professor Sohn’s work has been recognized through various awards: Distinguished Professor, 2014, University of Utah; 2014 Educator Award, TMS; 2012 Distinguished Scholarly and Creative Research Award, University of Utah; 2012 Billiton Gold Medal, The Institute of Materials, Minerals and Mining, U.K.; TMS 2009 Fellow Award in recognition of outstanding contribution to the practice of metallurgical/materials science and technology; 2001 James Douglas Gold Medal Award from AIME for leadership and outstanding contributions in research and education of nonferrous extractive metallurgy and for work related to the modeling of gas-solid reactors and development of novel solvent extraction systems; Fellow Award from the Korean Academy of Science and Technology, 1998; 1993 TMS Champion H. Mathewson Gold Medal Award for the most notable contribution to Metallurgical Science in the 3-year period; 1990 TMS Extractive Metallurgy Lecturer Award in recognition as an outstanding scientific leader in the field of nonferrous extraction and processing metallurgy; TMS Extraction and Processing Science Award (1990, 1994, 1999 and 2007); Fulbright Distinguished Lecturer (1983); and Camille and Henry Dreyfus Foundation Teacher-Scholar Award (1977). In 2006 TMS honored Dr. Sohn with the “Sohn International Symposium on Advanced Processing of Metals and Materials”.

Dr. Sohn has authored or co-authored 4 monographs, 21 ed. books, 23 book chapters, 530 papers, 5 patents, 37 technical reports, and has some 240 invited lectures, some 250 abstracts and presentations.  He has served as Director of TMS, and delivered numerous plenary lectures. He was a DOE Fossil Energy Lecturer, 1978–81, and was appointed Advisor to LS-Nikko Copper Co., Korea in 2005.

His current research areas are Novel Flash Ironmaking Technology; Inorganic Nano-Material Synthesis; Gas-Solid Reaction Analysis; and Flash Smelting Processes.
