Penelope King uses geochemistry and cosmochemistry to study planetary processes to better understand past and future planetary environments, and what this information may tells us about climate change. She is a professor at the Australian National University (ANU) in the Research School of Earth Sciences (RSES). King holds many awards, including Fellow of the American Geophysical Union and the Mineralogical Society of America in 2019, and winning the AGU Joanne Simpson Medal for Mid-Career Scientists the same year.
