About

Hyun-Joong Chung is an Associate Professor of Chemical and Materials Engineering at the University of Alberta. He leads an interdisciplinary research program on understanding physical and chemical properties of elastomeric materials, and then on translating the understanding to engineering applications in various fields. His early-career contributions include key studies on the role of jamming nanoparticles in phase-separating polymer blends. After spending 4-years in information display industry to develop zinc-oxide-based thin film transistors for AMOLEDs, he came back to academia to apply the device knowledge in stretchable bioelectronics. His recent contributions are on studying various stretchable soft materials, including gels, elastomers, and textiles with or without functional additives and reinforcements.

B.Sc. - KAIST (2000), PhD - U. Pennsylvania (2005), Senior Engineer @ Samsung Display (2006 - 2009), Post-doc - U. Illionois at Urbana-Champaign (2009 - 2012)
