My primary research interest is stretchable/flexible electronics, which offers high-performance electronic devices with the mechanical properties of a rubber band, which enables otherwise impossible applications, such as flexible display, bio-integrated diagnostic and therapeutic implements (e.g. flexible EKG sensors), bio-inspired devices (e.g. electronic eyeball cameras), and wearable electronics. The research topics include design and fabrication of stretchable electronic devices, mechanics of thin films on compliant substrates, and integration strategies for hard/soft materials. Nanomaterials, such as carbon nanotubes, silicon nanowires, and graphenes, possess extraordinary mechanical and electrical properties, and are good candidates for next-generation devices and electronic systems. Another focus of my research is theoretical study of mechanical behaviors of nanomaterials, and their interaction with substrates, through both analytical and atomistic methods.

MCEN 5930 - Professional Internship
Primary Instructor
-
Summer 2024
This class provides a structure for Mechanical Engineering graduate students to receive academic credit for internships with industry partners that have an academic component to them suitable for graduate-level work. Participation in the program will consist of an internship agreement between a student and an industry partner who will employ the student in a role that supports the academic goals of the internship. Instructor participation will include facilitation of mid-term and final assessments of student performance as well as support for any academic-related issues that may arise during the internship period. May be taken during any term following initial enrollment and participation in ME graduate programs. Department permission required to enroll. May be repeated up to 6 total credit hours.
