Research Statement

The Gingrich group applies analytical and computational methods to problems in statistical mechanics, stochastic thermodynamics, chemical kinetics, and biophysics. In particular, we seek principles and numerical techniques to describe nonequilibrium chemical dynamics. Inspired by biological systems that utilize chemical fuels to drive nonequilibrium processes, we aim to develop tools that can aid in the design of artificial systems with similar capabilities.
