My research group is devoted to obtaining answers and insight to important chemical problems in essentially every area of chemistry, especially biological and organic chemistry, through theory and computation rather than experimentation. Chemistry is largely governed by the physics of electrons. Because the quantum mechanical Schrodinger Equation, HΨ = EΨ, properly describes the physics of small objects such as electrons, its solutions can provide insight into the chemistry of atoms and molecules. Due to the complexity of the underlying mathematics, such solutions can only be obtained with substantial computational resources.

Of particular interest are weak chemical interactions (hydrogen bonding, van der Waals forces, pi-type interactions, etc.) that play a vital role in a host of chemical, physical, and biological processes. Using extremely accurate electronic structure techniques, we probe the details of the underlying physics behind these interactions. We are also developing new computational methods that can reliably describe weak chemical interactions in large chemical or biochemical systems.
