Welcome! We are a research group in the Materials Science and Engineering Department at the University of Pennsylvania, located in urban Philadelphia.

Our group aims to answer fundamentally inspired and technologically relevant questions about how advanced engineering materials undergo deformation.  The insight gained from our work will enable the design and use of next-generation computers, micro- and nanoelectromechanical systems (MEMS/NEMS), nanotechnological devices for medical, electronic, and sensing applications, and energy conversion and storage devices.  We use innovative and cutting-edge experimental techniques to study the complex interplay between events occurring at atomic length scales and macroscopic materials properties.  Equipped with knowledge about mechanisms for deformation in advanced materials, we strive to engineer and tailor properties for functional use.
