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. Currently, in collaboration with Dr. Yumin Li, we are investigating
the interaction of the tetramer
annexin A2/S100A(10/11) with a POPC/POPS/PI(4,5)P2/Cholesterol membrane.
