Research Interest

My general interest includes emission and scattering processes on airless objects in the solar system (theory, observation, experimental data analyses, data reduction and related statistics and coding).

Currently I am working at KASI (Korea) as a postdoc researcher for NASA's SPHEREx (solar system science & pipeline development).

In theoretical approach, the main topics I focus on are:

• Thermal radiation, radiation pressures from airless bodies.
• DESTINY+ mission related (3200 Phaethon).

In observational approach, the main topics I focus on are:

• Optical & near-infrared (NIR) polarimetry/photometry
• Experience in HAWAII infrared array, as well as optical detectors
• Experience in extra-effort for accurate photometry (flat-field analyses, statistics, instrument parameter analyses, absolute/relative photometry of trailed objects, ...)
• Experience in detector parameter analysis (gain, readout noise, waveplate rotation, ...)
