Research Interests

My research is eclectic. I study human histories of Geology, particularly the ways that Geology has interacted with colonialism. I'm the curator of the Bryn Mawr Mineral Collection, and I'm very interested in the ways that we present mineral displays to the public. I also study the mineralogy of Mars, using satellite data, and I do field research on Acid Mine Drainage sites, which often produce minerals in similar environments to past environments on Mars.
