Vita
Research Interests:
I am an experimental volcanologist and planetary scientists. I conduct experiments and use thermodynamic modelling to constrain the formation of planetary materials and use analytical tools to relate the results to samples, such as the rocks returned by the Apollo missions from the Moon. I also use spectroscopic methods to relate experimental results to observations of terrestrial planets by space missions, such as the BepiColombo probe to Mercury.
I am interested in how hot atmospheres interact with magma oceans on exoplanets, or rocky planet surfaces, such as on Venus. I work on new experimental designs to address these processes.
