Hello! I’m Alexandra and I am currently a second year undergraduate student majoring in geology with minors in physics and math. I joined the Glacier Modeling lab fall semester of my sophomore year and plan to continue working in the spring semester.

Project

Currently I am working as a research assistant for PhD candidate Naureen Khan. Using both Sentinel-1 SAR and Sentinel-2 images, I manually digitize labels of crevasse fields and supraglacial streams/lakes over the Greenland ice sheet in QGIS. These labels are then used to train MimiNet, a deep learning model developed by Naureen to help detect crevasse fields on the ice sheet. With the guidance of her and support from the lab, I have been able to practice my GIS skills and learn a lot about glaciology!

The image on the left is of a Sentinel 2 image of the glaciers I have been working on. The image on the right is the a Sentinel 1 image of the same area.

The image above is of a manually digitized glacier. Labeled in green are suspected crevasse fields and in blue are supraglacial streams and lakes.
