Professor Alexandra Navrotsky's research interests have centered on relating microscopic features of structure and bonding to macroscopic thermodynamic behavior in minerals, ceramics, and other complex materials. She has made major contributions to both mineralogy/geochemistry and to solid-state chemistry/materials science in the fields of ceramics, mantle mineralogy and deep earth geophysics, melt and glass science, nanomaterials, and porous materials. She has developed unique high-temperature calorimetric techniques and instruments and her laboratory the Peter A. Rock Thermochemistry Laboratory, collaborates with scientists all over the world.
