    BioI am interested in the fundamental problem of observing, understanding, and predicting the behavior of ice and water in the earth system. I am particularly interested in the role that subglacial water plays in the evolution and stability of continental ice sheets and their contribution to the rate of sea level rise. I am also interested in the development, use, and analysis of geophysical radar remote sensing systems that are optimized to observe hypothesis- specific phenomena. I consider myself an instrument scientist and seek to approach problems from both an earth system science and radar system engineering perspective. By focusing on the flow of information and uncertainty through the entire process of instrument development, experimental design, data processing, analysis, and interpretation, I can draw upon a multidisciplinary set of tools to test system-scale and process-level hypotheses. For me, this deliberate combination of science and engineering is the most powerful and satisfying way to approach questions in earth and planetary science.

    Current Research and Scholarly InterestsResearch
    I study active earthquake and volcanic process through data collection, inversion, and theoretical modeling. Using techniques such as the Global Positioning System (GPS) and Interferometric Synthetic Aperture Radar (InSAR) my students and I 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. We use these results to develop and test models of active plate boundaries such as the San Andreas, and the Cascade subduction zone, the nucleation of earthquakes, slow slip events, and the physics of magma migration leading to volcanic eruptions.

    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.

    Ph.D. Student in Geophysics

    Current Research and Scholarly InterestsMy research focuses on integrating remote sensing datasets to model and predict aquifer compaction and land subsidence as a response to groundwater pumping. Land subsidence is effectively measured using Interferometric Synthetic Aperture Radar (InSAR). InSAR data contain a wealth of hydrogeologic information, but are difficult to interpret without adequate knowledge of the pore pressure histories and geomechanical properties of the aquifers and aquitards that are compacting (which information is rarely available!). By integrating additional datasets, both remote sensing and in-situ, we are able to extract more useful hydrogeologic information from InSAR data.

    Some specific research projects I’ve worked on so far include processing Interferometric Synthetic Aperture Radar (InSAR) data; calibrating Airborne Electromagnetic (AEM) data with lithology; modelling groundwater diffusion; performing inversions; and using machine learning methods to integrate diverse datasets and aid in predictions.

  • Zack Spica

    Zack Spica

    Postdoctoral Research Fellow, Geophysics

    BioZack received his PhD in geophysics from the Universidad Nacional Autónoma de México, Mexico in 2015. His PhD was focused on imaging active volcanoes using correlations of ambient seismic field: a technique with which we can extract coherent waves propagating between seismometers by correlating interference patterns of chaotic waves. Zack joined the earthquake seismology group led by Greg Beroza in the fall of 2015. His research aims to gain a better understanding of the Earth via a combination of observational and interpretational work on seismic data. He is interested in imaging the Earth at every scale - i.e., from the shallow sub-surface to the deepest Earth interfaces such as the core mantle boundary -, understanding volcanic and hydrothermal systems and predicting ground motion caused by earthquakes. More broadly, the integration of his research helps mitigating the risks that certain and inevitable natural disasters pose to human populations.
