Professor of Chemistry
Quantum chemistry is the application of the physical laws of quantum mechanics to chemistry. Advances in theoretical algorithms and computer hardware have made quantum chemical computations an indispensable part of the modern chemist's toolkit. Molecular structures, reaction energies, and spectroscopic properties are now routinely calculated with a variety of available software packages.
Research in quantum chemistry is an enjoyable mix of mathematics, physics, chemistry and computer science. Particular projects may focus on the invention of new theoretical approaches and their implementation into computer programs, or with the direct application of existing methods to study chemical problems. Collaborating with colleagues around the country, I am a primary developer of the PSI quantum chemistry program. Much of my work has focused on the properties of molecules in electronically excited states.
My principal teaching duties are in General Chemistry and Physical Chemistry. In the general education curriculum, I have also taught Chance or Design: Our Place in the Cosmos and Modern Alchemy: Chemistry for the Non-Scientist.
My wife April and I are both from Indiana and met each other while attending Huntington University. Subsequently, we went to graduate school at the University of Georgia. We moved to Minnesota in 2001. We currently have an 9-year-old daughter, a 7-year old daughter, and a 5-year old son.
