Dr. Teun-Teun Kim received his Ph.D. in physics from the Korea Advanced Institute of Science and Technology (KAIST) in 2010. From September 2010 to August 2013, he was a Post Doctoral Research Fellow at KAIST, and from September 2013 to February 2017, he worked as the Marie Curie Fellow in the Metamaterial Research Centre at University of Birmingham, UK. In March 2017, he was awarded, IBS Young Scientist Fellowship and currently he is a research professor in IBS, Center for Integrated Nanostructure Physics at Sungkyunkwan University. Dr. Kim's work on Graphene Metamaterials was selected as "Best Basic Research 50 for 2013" by NRF(National Research Foundation) and introduced in Science and Nature Photonics, and Graphene Metalens's work was selected as "Best Research 10 for 2017" by IBS and received numerous media coverage. His current research focuses on photonic devices by using novel PT-symmetry and topological physics with metamaterials and plasmonics, and 2D materials photonics including graphene and transition metal dichalcogenide.
