About Me


I am currently a Research Scientist for the Pacific Northwest Seismic Network at University of Washington specializing in earthquake early warning. I completed my Ph.D. in Geophysics in 2013 at Scripps Institution of Oceanography.  Specifically, I use GPS instruments to model earthquakes and transient deformation. I am originally from Chicago and I attended Georgia Tech for my B.S. in Physics and M.S. in Earth and Atmospheric Sciences.

The underlying theme of my research is to model earthquakes and transient deformation events rapidly, efficiently, and with as little human intervention as possible using real-time, continuous, and campaign GPS measurements.  I am interested in problems across all spatial and temporal scales, and my work to date has fallen under the following areas:

  • Earthquake early warning using real-time GPS and seismogeodetic data (Crowell et al. [2009 - SRL], Bock et al. [2011 - BSSA], Melgar et al. [2012 - GJI], Crowell et al. [2012 - GRL], Crowell et al. [2013 - GRL], Melgar et al. [2015 - GRL], Crowell et al. [2016 - SRL])
  • Seismogeodetic analyses of different earthquakes (Geng et al. [2013-G3], Melgar et al. [2013 - GRL], Melgar et al. [2015 - JGR])
  • Automated detection of transient deformation in continuous GPS time series (Crowell et al., [2016 - JGR])
  • Interseismic deformation in the Salton Trough from high-density continuous and campaign GPS measurements (Crowell et al. [2013 - JGR])
