Curriculum Vitae:

Michaela Villarreal

My main research has focused on how the solar wind interacts with bodies that do not currently possess a dynamo. At Venus, I investigated how the ionosphere cam become magnetized during instances of high solar wind dynamic pressure. More recently, I have examined how solar energetic particle events may release subsurface water at Ceres to create a temporary atmosphere on the dwarf planet. At JPL I will be working on magnetohydrodynamic simulations of Jupiter's plasma torus with Europa.


Education

Research Interests

Small bodies, ocean worlds, and heliophysics


Projects

Dawn Icon Dawn
Dawn's goal is to characterize the conditions and processes of the solar system's earliest epoch by investigating in detail two of the largest protoplanets remaining intact since their formations.

Europa Mission Icon Europa Mission

NASA's Europa mission will conduct detailed reconnaissance of Jupiter's moon Europa to investigate whether the icy moon could harbor conditions suitable for life.
