Research Statement

The Freedman group applies the approaches and tools of synthetic inorganic chemistry to understand and overcome fundamental obstacles in physics and energy research. Synthetic inorganic chemistry will be used to target new systems, spectroscopy, crystallography, and magnetometry will be used to probe new compounds, and fundamental ligand field considerations will aid in interpretation of emerging physico-chemical phenomena and to predict new chemistry. Every student in our laboratory has the opportunity to learn synthetic techniques, crystallography, magnetism, and spectroscopy. Specific project areas are magnetism, superconductivity, and quantum computation.
