Areas of interest:

Micro- and Nano-electromechanical systems (MEMS/NEMS) sensors and actuators, microfabrication processes and materials, and computational modeling of micro-electromechanical systems. These interests are directed towards device development and engineering science in micro- and nano-technology, with an emphasis on acoustic sensing, wind tunnel instrumentation, dynamic systems, and robotic systems.
