Hi everyone πŸ‘‹

I am a Geologist and Potential Fields Geophysicist who recently (2023) finished my Ph.D. at the Victoria University of Wellington, in New Zealand πŸ‡³πŸ‡Ώ. I was part of the Antarctic Research Centre where I studied Antarctica's πŸ‡¦πŸ‡Ά Ross Ice Shelf with the use of airborne ✈️ geophysics data from the ROSETTA-Ice Project. I completed my undergraduate degree at Colorado College where I majored in Geology, and began learning about geophysics and Antarctica.

My PhD thesis can be accessed here, and the latex files and jupyter notebooks to create the figures are in this GitHub repository.

Python Packages

I currently maintain two Python packages:

  • PolarToolkit: This package provides many tools to help conduct polar/cryospheric research. This includes easily downloading a 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 gravity inversions for modelling the relief (topography) of an Earth layer. These layers are represented as a density contrast between the above and below materials. Common uses are modeling bathymetry (contrast between water and sediment), basement topography (contrast between sediment and crystalline rock), or the Moho (contrast between crust and mantle).

Research

past research πŸ’€: Determining magnetic basement topography beneath the Ross Ice Shelf (GRL paper)

basement repo card

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

inversion repo card

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

RIS inversion repo card

future research πŸ”œ: 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

Code
