Global Reference Surface Wave Data
How fast do surface waves travel globally after any earthquake?
Do we get the same information from various measurement techniques?
Which features in the Earth are robust and can be resolved by a reference model?
Checkout out results from the publication written in collaboration with 18…
Interactive Jupyter Notebook and Python Coursebook
How do we use Python and Jupyter notebooks to probe geoscience data and make real-world inferences?
Are there ways to make geoscience content more engaging with interactive and executable code?
How do we best incorporate geological, geophysical and engineering concepts in field trips?
Interactive Geophysics for Schools
What are the latest methods for probing the structure of the Earth's interior? What do seismic waves and tomographic models tell us about processes inside the Earth? How do we use seismology to teach cross-cutting concepts in our high schools?
Open Source Software
Why do we need a community toolkit for probing seismic models and data?
How do we make the tools web-based to reduce computational load on individuals?
Earth's Composition and Temperature
Is there a chemically distinct reservoir in the Earth?
Do superplumes overly denser-than-average material?
Can we detect these anomalies with seismic data?
This study presents the strongest evidence to date (ca. 2015) of large-scale thermo-chemical heterogeneities in the lowermost mantle using the full…
Flow in the Earth's mantle
What is the nature of flow in the mantle?
Where can radial anisotropy be robustly detected?
Can we reconcile a broad spectrum of seismic data? What are the benefits?
We use normal-mode splitting functions in addition to surface-wave phase anomalies, body-wave travel times and long-period waveforms to…
