D. Greg Walker

Associate Professor of Mechanical Engineering


Our mission is to explore the physical effects of energy transport particularly in nanoscale structures, and with this research we make engineering discoveries in energy applications. Specifically, we focus on modeling nanoscale energy transport (phonons, electrons, and photons) in solid-state devices. This includes thermoelectric devices, solar cells, and batteries, for example. We also study fundamental artifacts of small-scale transport such as thermal rectification and interfacial conductance in nanostructured materials.
