Dr. Jong Eun “Jon” Ryu joined NCSU in 2018. Dr. Ryu was an Assistant Professor at Indiana University-Purdue University Indianapolis (IUPUI) in 2013-2018. Dr. Ryu received his Ph.D. in Mechanical Engineering from the University of California, Los Angeles in 2009 and had received his BS and MS degrees from KAIST, Korea in 2004 and 2006, respectively. Right after his graduate research, Dr. Ryu completed a two-year postdoctoral training in the plasmonic sensors also at UCLA. Before he joined IUPUI, he worked for Intel Corp as a senior R&D engineer on the advanced semiconductor lithography technology.
Research Interests
Dr. Ryu’s research is focused on additive manufacturing, nanomanufacturing, and multifunctional composite materials with the applications of bio-inspired plasmonic sensing, tunable metamaterials, and 3-D printed stretchable electronics.
