Research Interests

Our research group is concerned with the development and application of the concepts and techniques of density functional theory to problems of chemical interest. Current studies focus on the application of density functional theory to environmental chemistry. In collaboration with scientists at the US Environmental Protection Agency, we are calculating gas phase thermo/kinetic properties of mercury and mercury containing compounds. We are also employing computational tools to elucidate the chemical processes that occur in our atmosphere. One project involves the determination of the 1-dimensional potential surface (PES) for the reaction of the OH radical with MPAN (methacryloylperoxynitrate) to product HAC (hydroxy acetone) and MAE (methacrylic acid epoxide). The resulting PES was used in a master equation solver to estimate the total rate constant for the reaction and to determine product yileds. We are using computational tools to explore the OH initiated oxidation of alkenes in the atmosphere under both low and high NOx conditions. We are also involved in using molecular dynamics to study protein-membrane interactions. A recent project involved the interaction of the binary complex of human tissue factor and factor VIIa with a POPC/POPS lipid bilayer. More ...
