Enabling Design for Additive Manufacturing Through New Metallic Alloy Development

Dr. Yongho Sohn is a Pegasus Professor and Lockheed Martin Professor of Engineering in the Materials Science and Engineering Department at University of Central Florida (UCF). He received his B.S. with honors and M.S. from Worcester Polytechnic Institute. He graduated in 1999 with Ph.D. from Purdue University, and spent two years as a post-doctoral research scholar at the University of Connecticut. He joined UCF in 2001 as an assistant professor to pursue his research and teaching interests in metallic alloy powder processing and additive manufacturing, microstructural analysis and control, multicomponent diffusion in multiphase alloys, metallic/ceramic coatings for high temperature applications, and metal-matrix composites. He is an elected Fellow of ASM International (FASM), recipient of NSF CAREER Award (2003), Outstanding Materials Engineer Award from Purdue University (2016), Korean-American Scientists and Engineers Association (KSEA) Engineer of the Year Award (2020), UCF Excellence in Research Award (2024; University Awardee). He is an Associate Editor for Journal of Phase Equilibria and Diffusion (Springer), a member editorial board for Metallurgical and Materials Transactions (Springer) and served KSEA as its 52nd President (2023-2024).
