Research Interests
- Development and the application of new methods in ab initio molecular orbital (MO) methods, centered around analytical energy derivatives and the use of these derivatives to explore potential energy surfaces
- Applications in a variety of areas including:
- Organic chemistry: reactions involving peroxides, peroxy acids and dioxiranes, reactivity and rearrangements of organic radicals, and the behavior of nitric oxide releasing agents
- Physical chemistry: reactions using embedded cluster methods and studying reaction path branching by ab initio trajectory methods
- Biochemistry: examining the modulation of chemical reactivity by interactions in the active sites of enzymes, for example carboxypeptidase inhibitors and phosphate transferases
- Materials science: Thermochemistry and reactivity of a variety of systems pertaining to silicon CVD (chemical vapor deposition), silane oxidation, Si-H-P, B-H-Cl and titanium-nitride CVD
