Professor Yang's research group is investigating Micro and Nano Opto Electro Mechanical Systems. In particular, the group is exploring carbon nanotube and graphene nanodevices as well as smart polymer devices for sensors/actuators and nanoelectronics/optoelectronics applications. Specifically, the group is working on graphene tunable photodetectors, solar cells and graphene/CNT supercapacitors, and tunable wetting devices based on smart polymers as well as MEMS actuators. Dr. Yang's research has broad implications that dramatically improve electrical/optical/mechanical properties of next-generation devices and provide unrivaled functionality for use in applications such as sensors, detectors, system-on-a-chip, system-in-a-package, programmable logic controls, energy storage systems and future electronic systems.
He has been the recipient of a number of awards, including NASA ICB Space Act Awards, Bonus (Level B and C) Awards and Class 1 NASA Tech Brief Awards. In recognition of his excellence in advancing the use of MEMS-based actuators for NASA's space applications, he received the prestigious Lew Allen Award for Excellence at JPL. Dr. Yang is currently PI/Co-PI on grants and contracts from AFOSR, NSF, NASA, SBIR, and US Army ARDEC. Dr. Yang holds over 10 patents issued or pending. He is Associate Editor and member of Editorial Board of the IEEE Sensors Journal. Dr. Yang is the director of Micro Device Laboratory, a Stevens's multi-user facility. |
