T. David Harris Assistant Professor

Research Statement

Our research employs a coordination chemistry approach to develop functional inorganic molecules and materials. Students in the Harris Group receive broad training in synthesis, by designing and preparing molecular complexes and coordination solids, as well as in physical methods, by investigating compounds using techniques such as X-ray crystallography, magnetometry, and spectroscopy. Our current interests lie in three main areas: (1) the design of high-spin transition metal clusters as MRI contrast agents, (2) the stabilization of reactive species and small-molecule catalysis in metal-organic frameworks, and (3) the synthesis of strongly-coupled one-dimensional coordination magnets.
