Associate Professor and Graduate Program Coordinator
Quantum Mechanics, Advanced Physical Chemistry, General Chemistry, Preparatory Chemistry
My research goal is to gain a fundamental understanding of complex chemical processes by merging theoretical calculations with results obtained through experimentation. When experimental data is not readily available, the goal is for theoretical predictions to serve as the driving force for future laboratory investigations.
Theoretical Characterization of Molecular and Cluster Anions
While numerous cations and their neutral counterparts have been well studied experimentally and theoretically, most anions are not well defined. Ab initio calculations are being used to characterize both ground and excited state properties of these systems.
Calculated IR Spectra
The ability to simulate IR spectra (frequencies and intensities) with existing ab initio methods is proving to be a successful link between my research group and the Environmental Protection Agency. Of current interest is the identification of individual structural isomers for compounds that are of environmental concern.
Nonlinear Optical Properties
Research in the area of ab initio Nonlinear Optical Properties for conjugated polymers is being conducted with collaborators at the University of California, Santa Barbara, the Universidade Federal de Pernambuco, and the University of Kuwait. The nature of this work involves testing convergence of the polarizability, and particularly the hyperpolarizability, with increasing chain length for a specific polymeric system. This work includes consideration of correlation effects, vibrational distortions and interchain interactions.
Local Quantum Chemistry
Research in the development of Local Quantum techniques is being conducted with the objective of computing large chemical systems without excessive computational demands. Projects focus on the use of the Local Space Approximation coupled with Hartree-Fock theory.
