about.
Grace Barcheck is an Assistant Professor in Earth and Atmospheric Sciences at Cornell University. Grace's work is focused on understanding deformation of geologic materials, especially frictional sliding at the base of ice sheets, and on tectonic faults that may or may not host earthquakes. Her work has implications for understanding two major Earth hazards: sea-level rise resulting from accelerated ice stream and glacier motion in a warming world, and earthquake hazards.

I am not currently looking for graduate students. Good luck with your search.
In glacial systems, Grace is interested in feedbacks between ice stream and glacier sliding speed and the evolution of the geologic materials (till, rocks, ice, and water) that comprise the sliding interface. She has a particular interest in basal micro-seismicity, or tiny stick-slips that happen on the ice sliding interface and reflect material and slip evolution beneath the ice. This work relies on geophysical data collected in-situ in Antarctica, Greenland, and Alaskan glaciers: passive seismic data, geodetic data, and ground-penetrating radar.
Grace is also interested in understanding controls on fault slip behavior, from earthquakes to slow slip. One way she studies this is through analysis of and comparison with the Whillans Ice Stream stick-slip cycle, which is an easy-to-observe analog to the earthquake cycle on tectonic faults. Another way is through exploiting modern machine learning methods to create and analyze very-complete earthquake catalogs in fault zones.

Grace is dedicated to understanding and addressing issues of justice, equity, diversity, and inclusion in teaching and research in STEM fields.
