RESEARCH OVERVIEW My research is a hybrid of geology and materials science, focused on the microscopic processes that give rise to attenuation – or the transformation of mechanical strain energy into heat. The work has applications to glaciers, ice sheets, and icy moons of the Outer Solar System, where attenuation of gravitational tides may be the key to understanding geophysical processes. My laboratory experiments explore the mechanical response of single and polycrystalline ice to tide-like forcing, using a standard materials testing apparatus modified by the addition of a custom cryogenic chamber. Cryogenic microscopy then allows me to assess the microstructures relevant to the observed response, linking mechanical behavior to microstructure.
