My research focuses on understanding the processes acting on the surfaces and interiors of the solid-surface planets and moons in our solar system. I am interested in geodynamic, tectonic, magmatic, hydrologic, and climatic processes, at scales ranging from local to global. To this end, I combine the analysis of gravity, topography, and other remote sensing datasets with numerical modeling. Current research interests include terrestrial planet tectonics, the gravity field and structure of the Moon, impact basins, volcanology on Mars, the hydrology and climate of Mars and Titan, and the evolution of Venus.
