About

David Catling is a Professor at the University of Washington in the United States. His research encompasses mineralogy, spectroscopy, and astrobiology, with a focus on planetary environments, water detection, and habitability in extreme conditions. Recent publications include studies on regolith in Jezero Crater, the dynamics of secondary atmospheres on exoplanets, and the implications of brine behaviors on Mars and Enceladus. His work contributes to understanding the geological and chemical processes that influence potential life beyond Earth.
