Welcome to the research group website of Asst. Prof. Hyeon-Ho Jeong in Gwangju Institute of Science & Technology (GIST), Republic of Korea. Our interdisciplinary research group is motivated to tackle challenges in a broad realm of 'nanotechnology' ranging from fundamental engineering to real-life industrial applications. We particularly focus on cutting-edge challenges in 3D nanofabrication, active metamaterials, chiral plasmonics, multifunctional nanocolloids, and biomedical micro- & nano-robotics.
