Dr. Chung's research focuses on astronomical instrumentation and observational astronomy, particularly building ground and space-based UV/Optical telescopes/instruments and studying circumgalactic medium and kinematics/dynamics of galaxies. He is the project scientist of the Aspera UV Small-Satellite Telescope mission, led by Dr. Carlos Vargas. He works on the FIREBall-2 UV balloon telescope mission, preparing its second flight. He also works on a high-resolution UV space telescope mission concept called Hyperion, led by Dr. Erika Hamden. He is interested in the morphology and kinematics of warm-hot CGM around the galaxy halos. During his Ph.D., he worked on building an optical multi-IFU spectrograph called DOTIFS. He also studies environmental effects on galaxy kinematics using SDSS MaNGA data and develops an IFU data post-processing technique (deconvolution).
