Joo-Hiuk Son received his BS and MS in electronics engineering from Seoul National University, Seoul, Republic of Korea, in 1986 and 1988, respectively, and his PhD in electrical engineering from the University of Michigan, Ann Arbor, in 1994. In the early years, his research was focused on the characterization of electrical and optical properties of semiconductors and various nanosized materials. In recent years, his interest has shifted to terahertz electromagnetic interactions with biological materials and their applications in medicine. Combining his expertise on nanomaterials and terahertz medical diagnosis, he invented a highly sensitive terahertz molecular imaging technique using nanoparticle probes.
