Biographical

Louise Kellogg is Professor of Geophysics at the University of California, Davis. Her research focuses on understanding the dynamics of the solid Earth and similar planets, focusing on understanind mantle convection and crustal deformation using computational models that are rooted in observation. Her research explores the physical processes driving mantle convection, the origins and scales of heterogeneity in the mantle, and the geochemical evolution of the planet through deep time. To address the large, complex datasets emerging in the geosciences, she established the W. M. Keck Center for Active Visualization in Earth Sciences (KeckCAVES). Through the KeckCAVES, her research expanded to include interactive visualization of data from natural disaster sites, reconstructing paleoocean flow, using virtual reality and augmented reality for research and outreach, and related topics. In 2010, she became the director of the Computational Infrastructure for Geodynamics (CIG), funded by the National Science Foundation to advance geophysics research through development and dissemination of high quality, open-source, scientific software. CIG's mission also includes preparing a cyberenbabled workforce by preparing geoscientists to use advanced computational methods, establishing partnerships between geoscientists, computational scientists, and mathematicians, and facilitating access to high performance computing for geophysics research. She was Department Chair for more than a decade, during which time the department grew into one of the top departments of geological sciences in the US for excellence and diversity in research and teaching.

Research

Cat in the Hat

The primary focus of my research is on understanding the flow in the Earth's mantle that drives plate tectonics, and observing and interpreting deformation in the Earth's crust. Within these broad catagories are a variety of projects:

Mixing

Mantle convection: At the elevated pressures and temperatures in the Earth's deep interior, rock responds to stress by slow, creeping flow. This flow drives plate tectonics, mountain building, earthquakes, and volcanic activity. Because the mantle is inaccessible to direct observation, we must use a variety of remote techniques and modeling to study mantle convection. At U.C.Davis, we use numerical methods to model aspects of mantle convection.

Earthquake Physics and Crustal deformation :
Understanding the behavior of the crust is essential to assessing seismic hazard of faults. It is important to know, for instance, what deformation takes place during the years between earthquakes on seismogenic faults. Yet, because large earthquakes occur relatively infrequently and because the rate of motion is small, the earthquake cycle remains poorly understood. Using space-based methods such as Global Positioning System (GPS), it has recently become possible to measure small motions in the Earth's crust inexpensively and quickly. Combining geodetic measurements with numerical modeling of deformation in the crust is enabling us to understand the way faults behave and how they interact. keckcaves

Visualization of geoscience data in an immersive environment: We are developing methods of interactive visualization, with a special focus on using immersive virtual reality (VR) environments to interact with models of Earth’s surface and interior. Virtual mapping tools allow virtual “field studies” in regions that are inaccessible to human geologists. Interactive tools allow us to manipulate shapes, while feature extraction tools support quantitative measurement of structures that emerge from numerical simulation. Visualizing stress and strain in high-resolution computer simulations of elastic-plastic deformation improves our interpretation of the dynamical processes that drive earthquakes. Reaping the full intellectual benefits of immersive VR requires us to tailor our approach to scientific problems that build on the visualization method's strengths, including both 3D perception and interaction with data and models, to take advantage of the skills and training of the geological scientists exploring their data in the VR environment. In doing so, we are developing a suite of tools that areadaptable to a range of problems.
