CURRENT POSITION

    NASA Postdoctoral Program (NPP) Research Associate, Planetary Geodynamics Laboratory, NASA Goddard Space Flight Center

RESEARCH Interests

    The characterization of planetary volcanic provinces through a combination of terrestrial field studies and spacecraft data analysis. My current research combines geomorphology, basaltic volcanology, planetary geology, field work, remote sensing, and GIS-based data analysis.
