Professional Interests

Our research is aimed to solve one of the grand challenges in modern chemistry: how to discover and design new functional materials that can be integrated into industrial importance devices, or serve as the basis for innovative new types of transformative technologies. We use techniques common to computational chemistry and informatics to provide new functional materials to address societal issues like energy independence and environmental sustainability; by combining rational chemical design, database mining, and first-principles calculations we can survey the properties of known and as yet to be synthesized families of solids. This helps us to gauge which known materials would benefit from a more thorough re-examination and which unknown materials would make exceptional candidates for synthesis and characterization. This approach relies heavily on concepts borrowed from inorganic chemistry, where the interplay of ionic radii, spin/oxidation state, and coordination environment help guide us towards exploring nature’s missing materials.

We use DFT methods to create structure-property relationships of a wide variety of materials classes such as metals, semiconductors, oxides, chalcogenides, nitrides, carbides, pnictides, and intermetallics to name a few, and connect the results of our calculations to available experimental data. Most of our projects are focused on determining what happens to both bulk and surface properties as the chemical environment is changed. For example, materials will behave differently in vacuum than they will in water, and they’ll go on to behave even more differently in the presence of an electrolyte! But what about replacing ions in a solid material? Substituting S2- for O2- in a complex metal oxide such as a perovskite doesn’t drastically change the overall oxidation states of the metals, but it will change the bond lengths, the size of the unit cell and the degree of electron sharing, which can all be computed with DFT.
