Research interests

Origin and evolution of planetary interiors and surfaces. Effect of volatiles, pH and oxygen fugacity on minerals and melts at high and low temperature. Parameters that affect spectroscopic features of glasses, sulfates and meteorites. Analysis of astromaterials - especially novel techniques for analyzing light elements, multivalent elements and trace elements - to better constrain genetic processes. Field analogs for Mars, Europa, Callisto, and Ganymede.

Researcher's projects

Dr. Penny King's research group examines surface and interior processes on planetary bodies. To achieve this goal, her research group attempts to understand the fundamental geochemical aspects of astromaterials under different conditions. Knowing how materials behave under different conditions allows us to predict planetary environments (in the past and future) and to make better tools to explore our solar system.

Research projects in the New MIRA lab investigate processes from the deep Earth to outer solar system.
