  • Brief Bio

    Kira Olsen uses machine-learning techniques and geophysical tools to answer fundamental questions about ice-covered environments. She is interesting in addressing key challenges in climate science by advancing understanding of the cryosphere-ocean-climate system. Kira uses ice-generated seismic events to study mass loss from the Greenland Ice Sheet, specifically iceberg calving, and to study ice-shelf fractures in Antarctica. She applies supervised- and unsupervised-learning approaches to detect and classify events in large observational datasets. She also applies understanding of ice dynamics and seismic-wave generation on Earth to investigate the surfaces and interiors of icy-ocean worlds, including Europa and Enceladus.
