Rayen School of Engineering



Dr. Jae Joong Ryu joined Youngstown State University as an Assistant Professor of Mechanical Engineering in Fall 2014. Dr. JJ’s background and research activities include in the areas of small-scale mechanics of microdevices, biomaterials, tribomechanical engineering and manufacturing. He received his B.S., M.S., and Ph.D. in Mechanical Engineering from Iowa State University in 2003, 2005, and 2009, respectively. His doctoral work focused on addressing a biomechanical damage mechanism of metallic implants. 
Before joined in Youngstown State University, he served as an Assistant Professor in the Mechanical of Engineering at the University of Texas at Tyler and Texas A&M University at Kingsville.
