Research Interests

Our group contributes computational and theoretical expertise to the CSMC research mission, offering fundamental understanding for both aqueous metal hydroxide clusters and amorphous oxide semiconductors, and translating discoveries to guide experimental efforts by research groups within the CSMC and beyond. While research in the group is computational, the ultimate goals in each area have broad scientific interest: first, we aim to develop a complete understanding of metal hydroxide clusters such that computations are no longer necessary to predict experimental outcomes or properties of these clusters; second, we are working to derive relationships between local structures in amorphous materials and their bulk electronic properties, providing direction for future synthesis of new semiconducting materials by inverse design.
