Career

He held two postdoc research positions with the first taking place in the Department of Physics at Seoul National University. During his doctorate program and first postdoc position, Choi observed that the cavity-QED microlaser system at MIT exhibits sub-Poisson photon statistics by measuring the second-order correlation which experimentally proved that the microlaser is a nonclassical source; a long-standing theoretical prediction. The second position was in the Michael S. Feld Group in the

George R. Harrison George Russell Harrison (July 14, 1898 – July 27, 1979) was an American physicist. Harrison became professor of experimental physics at the Massachusetts Institute of Technology (MIT) in 1930, and was appointed the school's dean of science in 1 ...

Spectroscopy Laboratory of MIT for a period of three and a half years in which he focused on biomedical optics. During this time, he invented tomographic phase microscopy which enables quantitative 3-D imaging of the refractive index of living cells and tissues of which a patent was later filed. He then implemented the first optical diffraction tomography of living cells which led to collaborative studies in biology and soft matter. These studies led to a new application area for digital holographic and interferometric microscopy. In September 2009, Choi returned to South Korea to work in the Department of Physics of

as an assistant professor. He became an associate professor in 2012 and a full professor in 2017. He is the principal investigator of the Super-depth Imaging Lab created in July 2016. The lab is within the IBS Center for Molecular Spectroscopy and Dynamics which falls under both the Institute for Basic Science and the Department of Physics in Korea University. Choi's research interests include ultrahigh-resolution deep-tissue imaging, control of wave propagation within scattering media, ultra-thin endoscopic microscope, and far-field control of near-field waves. The research direction of his laboratory is to resolve tissue turbidity for super-depth optical imaging, light manipulation and phototherapy.
