Biography

The Wang group at the University of Minnesota (UMN) focuses on the basic science and engineering of energy transport in nanostructured materials and across nanoscale interfaces. We explore the mechanisms through which light (photons, electromagnetic waves), charge (movement of electrons), heat (vibration of crystalline lattices), and spin (angular momentum of electrons) are converted to useful forms of energy (e.g., electricity), and their applications (e.g., electronic cooling and data storage). To achieve this, we invent and implement state-of-the-art ultrafast measurement methods to reveal the rich physics of heat and spin transport, which enables us to better design and optimize materials with desirable functionalities.
