I am a Postdoc at the Lamont Doherty Earth Observatory who usespotential fields geophysics to study the Earth beneath the Antarctic Ice Sheet!

I currently maintain two Python packages:

• PolarToolkit:This package provides many tools to help conduct polar/cryospheric research. This includes easily downloading and retrieving a wide range of datasets (i.e. imagery, topography, ice velocity), plotting functions for publication-quality maps and cross-sections, and many other helpful functions.

  

• Invert4Geom:This package allows users to perform 3D geometric gravity inversions for modeling the relief (topography) of an Earth layer, such as the Moho, the sediment-basement contact, or bathymetry. This package includes function for performing stochastic uncertainty analysis to give spatially-variable uncertainty estimates.

  

past research 💤: Determiningmagnetic basement topography beneath the Ross Ice Shelf (GRL paper)

current research ⏳:Developing aconstrained geometric gravity inversion algorithm, aimed at modeling density contrasts such a the Moho or basement

Developing a sub-Ice Shelfbathymetry model from the inversion of airborne gravity data

future research 🔜: Expanding the usability and documentation of the above inversion!

Other research interests include:

• geologic controls on ice dynamics
• various applications of geometric non-linear gravity inversions
• groundwater interactions with sub-ice hydrologic system
• tectonic development of the Ross Embayment

🔐 Check out the great Python packages fromFatiando.
