Yooseob Song, Ph.D., P.E. is an Assistant Professor in the Civil and Environmental Engineering Department. Before joining the University of Alabama in Huntsville, he worked as a tenure-track assistant professor at the University of Texas Rio Grande Valley for three years. Dr. Song obtained a bachelor's and a master’s degrees from Hanyang University, Seoul, South Korea, and a doctoral degree from Louisiana State University. He has several years’ industry experience as a professional structural engineer at TESO engineering Co., Ltd. He is also a registered Professional Engineer (P.E.).

Dr. Song’s primary research is in analytical and numerical aspects of solid mechanics. Specific interests include strain gradient continuum and crystal plasticity, crystal plasticity finite element method, AI assisted design of high-entropy alloys, mechanics of high-entropy alloys, numerical analysis of extreme loadings, piezoelectric energy harvesting, and high-performance cluster computing. He has authored 1 book, 2 book chapters, and +30 journal papers.
