Our group's interests are focused on new nanomaterials as well as micro- and nanoelectromechanical systems (MEMS/NEMS) for new applications in energy conversion. We create new mechanical metamaterials, including the thinnest plates that can be handled with bare hands. We also design and test new types of devices, such as microfabricated thermionic energy converters, which convert heat directly to electricity at very high temperatures by literally boiling electrons off a surface and using them as a “working fluid” in a heat engine. We are a multidisciplinary group at Penn, engaged in research at the intersections of mechanical engineering, electrical engineering, materials science and engineering, and applied physics.

We are often looking for motivated new group members: see Openings
