Biography

I am a JPL Postdoctoral Fellow in the Sea Level and Ice Group whose research centers on the interactions between the solid-Earth, ice, and oceans. At JPL, I am investigating the influence of 3D lateral variations in Earth viscosity structure on the glacial isostatic adjustment (GIA) process and its signal in geodetic datasets, particularly GRACE. I started my earth science journey with a background in geology and mathematics before shifting to geophysics for my PhD, where I studied the influence of geodynamic factors like mantle flow and GIA on intraplate stress, fault stability, and seismicity in eastern North America. I also conducted research on subduction tectonics and developed a Bayesian gravity inversion software for modeling 3D subsurface density structure. I am interested in growing my expertise in different geodetic techniques and datasets and the application of those data to informing our understanding of surface water mass balance and sea level rise, as well as geological, climatic, and coastal hazards. In addition to doing science, I enjoy baking, cooking, all things food and drink, and being outdoors.
