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.

1. Understanding the thermostability of the materials in nuclear reactors, including molten salt reactors 

2. Safe disposal of nuclear materials to decrease as much as possible the harm to the environment.

Energy materials have a wide range of applications such as fuel cells, battery cells, and water splitting. Understanding these materials' thermodynamic capabilities is needed to improve performance under operating conditions, reduce decomposition, and reduce unwanted reactions.



Zeolites are catalysts for a variety of organic chemical reactions and have a multitude of applications.



Material stability on Earth and other planets have environmental ramifications to better understanding material decomposition and whether those release nutrients (i.e. iron) or contaminants (i.e. nickel).
