Research

Most of our research involves the measurement of short- to intermediate-range structure in silicate and oxide materials, although we occasionally work on other materials such as fluorides and even biological solids. In many cases, questions involve the nature and extent of structural disorder, whether this involves mixing of cations on sites in a mineral or ceramic, the network linkages in a glass, or the role of "defect" species that contribute disproportionately to the overall energetics. Our overall goal is to constrain models that can be used to understand and predict physical and chemical properties; our major research tool is solid-state Nuclear Magnetic Resonance (NMR) spectroscopy.
