Research Description

Please note: I retired on Jan. 1, 2012 and I will not be taking new students. However I remain active in the area of computational chemistry, and as a consultant.

Computational Chemistry. We have undertaken several computational studies based on student projects in undergraduate lecture and lab classes. These take advantage of UAF's excellent facilities for computational chemistry of the Arctic Region Supercomputing Center and the department's WebMO-Gaussian09 facility. Several projects concern the properties of non-covalent complexes of carboxylic acids and nitrogenous bases with various partners such as sulfur dioxide.  Other projects relate to the possible occurrence of low-barrier hydrogen bonds in enzyme active sites, computational studies on cyclodextrins and modified cyclodextrins (collaboration with Tom Green), and mechanisms of Lewis acid-catalyzed Diels-Alder reactions (collaboration with Tom Clausen).
