Philosophy

“Teaching at a research university requires a conscious effort to balance obligation to the student (in particular the undergraduate) with the time constraints imposed by an ever-increasing demand in research endeavors. Yet, by instilling the current cutting-edge research into the classroom, one can provide not only a unique opportunity to make learning more interesting and motivating to the students, but also inspire them to pursue advanced studies in MS and Ph.D. programs. I strongly feel that an active role in research is indispensable for effective teaching at the graduate level and for supervision of doctoral students. Integration of teaching and research in the classroom also adds enthusiasm and motivation to learning at the undergraduate level.

This philosophy has been shaped by my experience starting from my education at the University of Illinois, my work experience at Boeing, NASA, and at the Air Force Research Laboratory, as well as my 22 years of teaching undergraduate and graduate courses at NC State University.

My teaching philosophy consists of three distinct goals: (1) to guide students to develop their critical thinking skills; (2) to help students to establish a strong foundation in fundamental concepts and to develop problem-solving strategies. This can only be gained through examples, problems, and hands-on experience. i.e. “teach them how to fish instead of just feeding them fish;” and (3) to share the excitement about new and rapidly growing interdisciplinary fields and leverage my experience in research to teach lessons that will be of real use to the students.” – Dr. Yuan, 2012

Current Research

Yuan’s research represents the forefront of innovation in the development of advanced structural health monitoring systems and methods, which will immensely influence the future design and maintenance of structures, while providing for increased public safety in civic environments. Advanced structural health monitoring is expected to lead to significant decreases in maintenance costs for aerospace, mechanical, and civil structures, while increasing asset availability, and extending the life of structures. This will be achieved by employing advanced micro and nano sensors and actuators, which would serve as the “nerves” of the structure, being able to yield increasingly accurate measurements and predications of damage and degradation accrued by structures during their life cycle.

At NIA, Yuan’s research is focused on smart aircraft structures for structural health management and condition-based maintenance. Research thrusts include: composite material state awareness (damage state models, virtual load sensors, NDE inverse problems); structural health monitoring (multifunctional materials, damage detection and assessment); and health management (out-of-autoclave composite repair, smart repair, repair durability in damage tolerant and fail safe designs).

 Looking forward, Yuan endeavors to establish a multi-university, collaborative environment that would advance research and technology regarding sensors, actuators, microprocessors, signal processing, decision making algorithms, mechanics, and materials and structures as fundamental engineering tools for designing and building intelligent structures with multi-functionalities.
