About

I am interested in questions where progress towards a solution requires that connections be made across boundaries, where there are opportunities to contribute to ideas and initiatives larger than can be undertaken by any individual.

In pursuit of these question and communities, I contribute to projects including open source software for computational geophysics and open access educational resources for the geosciences.

Currently, I am a postdoc in the Statistics Department at the University of California Berkeley. I work on data science and interactive computing with Jupyter in the geosciences.

I completed my PhD in 2018 at the University of British Columbia where I study numerical geophysics and imaging methods with the team at the Geophysical Inversion Facility.

SimPEG

Simulation and Parameter Estimation in Geophysics

  • 2013 - Present
  • SimPEG is an open source python package for numerical simulations and gradient based inverse problems in geophysics. We are working to bring all of the geophysical methods into one place and into the open. Join the development on github!

    GeoSci.xyz

    Collaborative, open access educational resources for geophysics.

  • 2014 - Present
  • Web-based resources for the fundamentals of geophysics for practicing geoscientists (GPG) and electromagnetic geophysics (EM). These are collaboratively developed resources and include interactive numerical simulations.

    DISC 2017

    Short course on Geophysical Electromagnetics: Fundamentals and Applications

  • 2016 - 2017
  • I was a co-instructor for the Society of Exploration Geophysics Distinguished Instructor Short Course (DISC) led by Dr. Douglas Oldenburg. The course was delivered in 25 locations worldwide.
