Ki-Weon Seo is an associate professor in the Department of Earth Science Education at the Seoul National University. His research mainly focuses on examining ice mass loss from both ice sheets and sea level rise by using satellite gravimetry and altimetry data and currently covers regional sea level variation determined by gravitational change over West Antarctica.

Seo is a co-principal investigator on the LIONESS-TG project. He and his team will study ice mass loss in Thwaites Glacier that is one of the leading causes for the change of gravity.
