Youngjae Kim is a researcher in high‑temperature superconductor (HTS) magnet technology at the Applied Superconductivity Center (ASC) of the National High Magnetic Field Laboratory at Florida State University. Since 2014, he has been involved in the development of Bi‑2212 conductor and coil technology for next‑generation high‑field magnet systems. Prior to joining ASC, he worked as a postdoctoral researcher at the Massachusetts Institute of Technology, where he contributed to the development of no‑insulation ReBCO winding technology. He earned his Ph.D. in Electrical and Electronic Engineering from Yonsei University, Korea, where he studied superconducting fault current limiters and magnet applications using Bi‑2223 and YBCO conductors.
