Our research investigates the transport, conversion, and control of thermal and electrical energy. We are interested in both the fundamental limits of phonon and electron transport, and in materials or devices that can better control this energy. This research is applied to engineering challenges in heat transfer, energy conversion, and electron devices. We use a range of experimental methods that connect atomic structure to macroscale properties. This includes Raman spectroscopy, nanoscale fabrication, and rigorous electrical and thermal transport measurements. Below are some cool pics from our research for aspiring researchers.
