I received a PhD for quantum plasmonics in 2011 from the group at Hanyang University (Korea). Then I have worked as a postdoctoral fellow at Hanyang University (Korea), Centre for Quantum Technologies in National University of Singapore (Singapore), and Korea University (Korea) before I joined Karlsruhe Institute of Technology in 2016. Now I am working at Institute of Theoretical Solid State Physics in Karlsruhe Institute of Technology (Germany) with Prof. Carsten Rockstuhl. My current research interests include various topics aiming to understand quantum features in nanophotonic platforms.
