Research Overview:

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. In collaboration with Professor Hancock at the University of North Carolina Willington, we are employing density functional theory to predict the formation constants of metal-ammonia complexes in aqueous solution. This work will produce insights into theories of metal complex-formation reactions such as the functioning of metalloenzymes. Another project explores the hydration patterns of aldehydes and amides. We are also involved in protein structure modeling. Current studies include modeling bioactive proteins (toxins) in the venom of American scorpions. Another project involves using molecular dynamics to study protein-membrane interactions. See more at Dr. Bartolotti's website.
