Bio

As the dimensions of energy conversion and electro-mechanical devices approach the nanoscale, continuum theories cannot predict their behavior. Atomic-level simulations provide an opportunity to make such observations and to identify important physical mechanisms. Professor McGaughey's group uses molecular dynamics simulations, lattice dynamics calculations, and density functional theory calculations to understand material behavior at the atomic level. While based in mechanical engineering, the work draws tools and inspiration from materials science, physics, and chemistry.

Previous efforts include: how the thermal conductivities of superlattices are affected by their atomic structure, fluid flow and heat transfer in carbon nanotubes, and the development of methods for predicting phonon properties.

Current projects include: using quantum mechanics-based calculations to predict thermal properties, identifying the mechanisms involved in nanoscale copper oxidation, studying heat transfer in carbon nanotube networks, and probing the mechanisms of phase change in Ge-Sb-Te compounds.
