I’m a postdoc at NASA’s Goddard Space Flight Center and the University of Maryland -specializing in Arctic and Antarctic sea ice variability. I apply statistical/geospatial analysis, machine learning, and visualization techniques to a wide variety of polar climate datasets (modelled and observed), all primarily in Python. I also develop and run sea ice models (although not so much recently). Take a look around! Contact details below..
