BioMy research focuses on advancing the scientific and technical foundations of geophysical ice penetrating radar and its use in observing and understanding the interaction of ice and water in the solar system. I am primarily interested in the subglacial and englacial conditions of rapidly changing ice sheets and their contribution to global sea level rise. However, a growing secondary focus of my work is the subsurface exploration of icy moons. I am also interested in the development and application of science-optimized geophysical radar systems. I consider myself an instrument scientist and strive to approach problems from both an earth systems science and a radar systems engineering perspective. I am actively engaged with the flow of information through each step of the observational science process; from instrument and experiment design, through data processing and analysis, to modeling and inference. This allows me to draw from a multidisciplinary set of tools to test system-scale and process-level hypotheses. For me, this deliberate integration of science and engineering is the most powerful and satisfying way to approach questions in Earth and planetary science

I study active earthquake and volcanic process through data collection, inversion, and theoretical modeling. Using methods such as precise Global Positioning System (GPS) positioning and Interferometric Synthetic Aperture Radar (InSAR) we are able to measure deformation in space and time and invert these data for the geometry of faults and magma chambers, and spatiotemporal variations in fault slip-rate and magma chamber dilation. The accumulation of shear strain in tectonic regions provides a direct measure of earthquake potential. Similarly, magma accumulation in the crust prior to eruptions causes measurable inflation. We use these data to develop and test models of active plate boundaries such as the San Andreas, and the Cascade and Japanese subduction zones, the nucleation of earthquakes, slow slip events, induced seismicity, and the physics of magma migration leading to volcanic eruptions. These physics-based models rely on principles and methodologies from solid and fluid dynamics.
I teach introductory undergraduate classes in natural hazards and the prediction of volcanic eruptions, as well as graduate level courses on modeling earthquake and volcano deformation and geophysical inverse theory.

BioBefore joining Stanford in January 2014, I held a position as Lecturer in Applied Mathematics and as a Ziff Environmental Fellow at Harvard. I hold a PhD in Geophysics from MIT and a Master in Public Administration from the Harvard Kennedy School. Prior to joining graduate school, I worked as a scientific consultant for different international organizations aiming to reduce the impact of natural and environmental disasters in vulnerable communities. The goal of my research is to advance our basic understanding and predictive capabilities of complex multi-phase flows that are fundamental to Earth science. I pursue this goal by developing original computational methods customized for the problem at hand. The phenomena I explore range from the microscopic to the planetary scale and space a wide variety of geophysics systems such as volcanoes, glaciers, and magma oceans. I have taught both undergraduate and graduate courses in scientific, planetary evolution, and natural disasters. Since arriving at Stanford in January 2014, I have co-taught GES 118, Understanding Natural Hazards, Quantifying Risk, Increasing Resilience in Highly Urbanized Regions
