Sejeong Kim graduated from Sogang University, Korea in 2009 with a degree in Physics and Integrated Biotechnology. She received her Ph.D. in Physics from Korea Advanced Institute of Science and Technology (KAIST) in 2014. Dr. Sejeong Kim spent two and half years as a postdoctoral researcher at KAIST. She joined the University of Technology, Sydney (UTS) as a postdoctoral researcher since 2017. Her doctoral research interests include semiconductor optical resonator design, fabrication and optical characterization. The title of doctoral thesis is “Study of photonic crystal nanobeam lasers and their applications”. Since then, her interest was to efficiently collect light from GaN single emitters. Sejeong Kim’s research at UTS will focus on the introduction of micro/nano cavities for new materials.
