About

I am a research scientist studying ice sheets and polar oceans as indicators of climate change. I am formally trained as a computer scientist and earth scientist focusing on polar glacier hydrology and oceanography. I regularly work or have worked in the following areas:

  • Collecting data from remote field sites such as underneath a glacier, within a crevasse field, or from the ocean at the edge of calving glaciers.
  • Leading logistically complicated field campaigns with international stakeholders and participants ranging from multi-national corporations to Ph.D. students.
  • Custom or novel sensors design, development, construction, deployment, operation, and field repair/debugging.
  • Reproducible computational workflows and scientific publications using open source tools.
  • Climate modeling including coupling ice sheet and global climate models.
  • Remote sensing spacecraft operations and mission control, sensor calibration, and end-user imagery use.
  • Public outreach and education including popular press interviews, museum display creation, and speaking engagements on all seven continents from the U.N. General Assembly Room to kindergarten classrooms.

For more information, please read the relevant publications or my CV.
