Sarah Stewart’s research group investigates the formation and evolution of planetary bodies. Our primary techniques are shock wave experiments to measure material properties and numerical simulations of planetary processes. We tackle a broad range of problems in planetary science by focusing on understanding the feedbacks between physical processes and changes in material properties.

Where did the Moon come from? A new theory.


September 2018: We are pleased to announce the launch of CLEVER Planets (the Cycling of Life-Essential Volatile Elements on Rocky Planets), a NASA NExSS team investigating the necessary chemistry for a rocky planet to host life.

Sarah Stewart is a Co-PI on the new DOE-NNSA Center for Matter at Extreme Conditions. She will use shock physics experiments to study the physical properties and equations of state of planetary minerals and gases at extreme pressures and temperatures. These data will be used to understand the interior structures of planets and the outcomes of planetary collisions. The Center is led by Professor Farhat Beg at U. California San Diego.
