Research Description

The Loring Group develops statistical mechanical methods to study molecular motions and dynamical processes including reaction kinetics, transport, and spectroscopy.

The dynamics of molecules in condensed phases control phenomena ranging from biological processes to the course of liquid phase chemical reactions to the mechanical properties of materials. Our group develops theoretical methods for interpreting and predicting the motions of both small molecules and macromolecules in the liquid state. A principal research area is the development of semiclassical approximations to quantum mechanics that can be applied to the interpretation of multidimensional infrared spectroscopy of biomolecules.
