Prof Brittany Erickson Receives Two Competitive NSF Grants

Dr. Brittany Erickson is an assistant professor in the CIS department. She came to the University of Oregon in 2018 after spending 4 years at Portland State University.  Her areas of expertise are in scientific computing and numerical methods for partial differential equations, applied to problems in geophysics.  She is co-leader of the Southern California Earthquake Center’s working group for advancing codes for simulating earthquake sequences, involving 30+ scientists from over 10 countries. 

Dr. Erickson recently received two competitive NSF awards:

#1 Collaborative Research: Exploring System-Wide Events on Complex Fault Networks using Fully-Dynamic 3D Earthquake Cycle Simulations (3 years, $489,000).

This grant will support Dr. Erickson and Dr. Jeremy Kozdon (an applied mathematician from the Naval Postgraduate School) in developing a large-scale, high-performance computing framework for modeling system-wide earthquakes in complex fault geometries, with full dynamics in 3D volumes. The PIs will apply their recently developed hybridized numerical scheme for simulating long-term earthquake activities and leverage state-of-the-art algorithms and high-performance computing to develop a large-scale, physically robust, predictive modeling framework of earthquake source processes. Outcomes from this work will shed light on our understanding of the physical settings in which the world’s largest earthquakes occur.

#2 Fluid Oscillations in Conduit-reservoir Systems, Very Long Period Seismic Signals at Kilauea Volcano, and the Phenomenology of Unsteady Magma Ascent (2 years, $287,000)

This grant will support Dr. Erickson and Dr. Leif Karlstrom (a volcanologist from the University of Oregon) in developing an advanced scientific computing framework for studying unsteady motions of magma hidden below Earth’s surface in order to understand the physical processes that give rise to volcanic eruptions.  This work will increase our understanding of volcanic eruptions and their associated human hazards, helping bridge the gap between geophysical observations, volcano physics, and advanced numerical methods.
