About

Seho Kim is an Assistant Professor at the Hawaiʻi Institute of Geophysics and Planetology (HIGP), a faculty member of the Hawaiʻi Space Flight Laboratory, and Cooperating Graduate Faculty in the Department of Earth Sciences at the University of Hawaiʻi at Mānoa, joining in 2026. Kim's research uses radio signals (signals of opportunity, GNSS reflectometry and radio occultation) to sense the ionosphere, soil moisture, sea ice and snow, and to probe planetary magnetic fields and gravity.

Before UH, Kim was a postdoctoral fellow in the Radio Science and Solar System Radar Group at NASA's Jet Propulsion Laboratory (2023–2025). Kim received a Ph.D. in Aeronautics and Astronautics from Purdue University in 2023 (dissertation: Multiple Signals of Opportunity for Land Remote Sensing), and an M.S. in Electronic and Information Engineering (2018) and a B.S. in Electronics and Avionics Engineering (2016, magna cum laude) from Korea Aerospace University.
