Research Areas

Dr. Wehmeyer uses experimental and theoretical techniques to study heat transfer, with an emphasis on nanoscale heat conduction. This research is motivated by applications such as microelectronic thermal management, solid-state energy conversion, and heat-assisted magnetic recording, all of which require a detailed understanding of how heat is conducted through nanostructures and across interfaces. Dr. Wehmeyer seeks to first understand the mechanisms of heat transfer at small lengthscales, and then to use this fundamental knowledge in the design of macroscopic thermal management and energy conversion technologies. Research projects of current interest include developing ultra-high spatial resolution temperature mapping tools, measuring thermal properties of anisotropic thin films, modeling heat transport in superlattices, and building active and nonlinear thermal systems for improved thermal control.
