Wonjin Choi

Degree: Ph.D. from the University of Michigan
Research: Chiral Phonons and Terahertz Optics
Joined LLNL: June 2022

Research at LLNL: Wonjin is aiming to develop reconfigurable metamaterials for THz beam modulation and advance the practical realization of chiral terahertz spectroscopy, which is a promising tool for biomedical technology and biological and chemical security. As plastic explosives, fertilizer bombs, and chemical and biological agents become increasing threats, and the transportation of illegal drugs and adulteration of food develops, effective means for rapid detection and identification of these threats is required. THz spectroscopy could provide high-throughput screening method with accurate molecular information to combat this growing issue.

Bio: Wonjin Choi is a Lawrence Fellow in the Physical and Life Sciences Directorate. He earned his B.S. and M.S. in Materials Science and Engineering from Yonsei University. After graduation, he began work at Korea Research Institute of Chemical Technology (KRICT) fabricating nanodevices with nanomaterials including CNT and graphene. He received his Ph.D. from the University of Michigan in 2021. His thesis focused on the investigation of terahertz optics and chiral phonons.
