My research focuses primarily on charge transport in biological systems and nanomaterials. Very small things, such as atoms, tend to behave more like waves than particles when they are observed on a very small scale. We are currently exploring how these wave-like (quantum) properties of light nuclei influence the rate of charge transfer in these systems. We construct models which can compute physical properties of these systems and then use powerful computers to perform calculations that help us understand how these systems operate.
