I am a structural geologist interested in the interaction and coexistence of brittle and ductile structures in rocks. To investigate the impact of complex rheologies on the formation of such structures I am using a combination of physical modeling, numerical modeling, and field work. In the structural experiment lab at ISU I use a wide variety of analog materials ranging from silicone and sand to polymers to simulate the behavior of rock in different deformation regimes. I combine the lab results with field observations and numerical models to investigate the physical processes leading to stunning and complex deformation patterns in nature.
