Research involves the determination of mineral structures using x-ray diffraction data in order to address a wide variety of Earth-related problems including: the crystal chemical behavior of mantle minerals, the effects of Cl in biotite and amphibole, the shape of atoms in minerals as related to bond type, and the effects of cation ordering in micas. Additional applied studies include: study of natural analog minerals to evaluate potential nuclear waste forms, structure determination of organo-metallic molecules, and evaluation of the structural state of semi- and super-conducting materials.
