Research Interests

Computatinal Quantum Chemistry

Computational quantum chemistry, using ab initio molecular orbital and density functional theory, is being employed to determine molecular structures, spectroscopic characteristics, energy levels of molecules and potential energy surfaces, and to help understand how molecules react with one another. Major applications include catalysis, reactive intermediates, intermolecular interactions, gas-phase ion chemistry, free radical reactions, organic reaction mechanisms and sulfur chemistry. Another major research interest is the development of efficient and accurate methods to study structures and properties of molecules in solution. Recent research activity has focused on modeling of molecular sensors, hydrogen storage materials, transition metal complexes, and compounds of medicinal and biological importance.
