How do crystal structures interact with the geological environment and how can society use them for new technologies? 

Hydrous minerals

Understanding the distribution and geological significance of water within Earth helps us develop models of how water circulates deep within our planet, as well on the surface of Mars.

Mineral systematics

We are studying the fundamentals of mineral diversity as a record of the dynamic geological and environmental processes that have shaped Earth.
