Claire Harrigan
Visiting Assistant Professor of Earth and Oceanographic Science
As a geochronologist, I date rocks to understand how Earth systems evolve with time. I use the minerals zircon and titanite to date granites from shear zones to understand the rate of mountain-building processes at continental margins. I have also worked on refining the geologic time scale, modeling the rate at which the crust cools after being hit by a meteorite, and understanding student awareness of Earth science careers. If you are interested in doing research with me, please reach out!
