About
Dr. Ko, Kyung-Tae received BS and Ph.D. in experimental physics from POSTECH, South Korea. He studied multiferroic ferrites, layered manganites, and transition metal-based nano compounds for his thesis research. He is an electron spectroscopist and expertized in XAS, (AR)PES, RSXS techniques using synchrotron radiation sources. His main interest is investigating the electronic structure to explain the correlated phenomena in the various transition metal-based complex materials including oxides, chalcogenides, and intermetallics. After two years postdoctoral fellow in POSTECH, he joined in the Max Planck POSTECH Center as a junior research group leader and worked as a guest scientist in MPI-CPfS, Dresden, Germany until October 2015. Returned to Korea, he worked as a senior scientist in Max Planck POSTECH Center, and as an affiliate professor in Dept. Physics, POSTECH until December 2019. In 2020, he moved his position to Korea Basic Science Institute and worked in the Division of Material Analysis and Research and Division of Large Research Infrastructure Project to participate in a new synchrotron radiation source. Now, he is working in the multipurpose synchrotron facility project, continuing his study on the correlated electronic and magnetic materials.
