Research interests include the design, fabrication, and testing of micromechanical and nanomechanical devices, developing novel methods to realize nanoscale devices for use as sensors and actuators, studying the non-linear dynamics of M/NEMS resonators and oscillators, including synchronization and modal coupling, studying plasmonic behavior and light scattering, ranging from Rayleigh to Mie, for the formation of metamaterials, including applications such as flat lenses, and creating quantum systems of quantum dots coupled with mechanical vibration to a carbon nanotube.
