Summary
Professor Yuen has over 40 years of teaching experience at the university level, for 34 years at the University of California at Santa Barbara (UCSB) and 5 years at the Hong Kong Polytechnic University (PolyU). Since September 2016, he has taken on a new role as a Lecturer at the Department of Mechanical Engineering at Santa Clara University.
During his tenure at UCSB, his teaching focused largely on areas related to his research, thermodynamics, fluid mechanics and heat transfer, both at the undergraduate and graduate level. In 1980, he received the Ralph Teetor Award from the Society of Automotive Engineering in recognition for his excellence in teaching in heat transfer.
At PolyU, Professor Yuen served as Vice President for Academic Development and in charge of developing a 4-year curriculum when PolyU is making a transition from a 3-year undergraduate program to a 4-year undergraduate program in 2012. As part of the undergraduate General University Requirement, he guided the Institution to adopt a 3-credit Service Learning requirement for all undergraduates. This is a historical achievement as PolyU is the first major university to adopt academic credit-bearing Service-Learning as a graduation requirement for all undergraduates. In addition to the administrative effort to develop the requirement for the Institution, Professor Yuen also participated in teaching classes in Service Learning, together with his colleagues. He traveled to Cambodia, Myanmar, and Rwanda to do service projects with students and his colleagues. After he returned to UCSB in 2015, he taught a class entitled “Appropriate Technology in the Developing World”, introducing UCSB undergraduate students to the concept of appropriate technology and servicing the community in developing countries.
Currently, he is enjoying his new role as Lecturer at the ME Department of Santa Clara University.
Service Learning
In the area of service-learning, Professor Yuen’s most important accomplishment is his effort to adopt Service-Learning as a graduation requirement for the undergraduates at the Hong Kong Polytechnic University. Many people have expressed interest in learning how this was achieved. As a matter of record, the following is an article written by Professor Yuen to reflect on this important event in his life. All events cited in this article are factual, from Prof. Yuen’s perspective. Please follow the link below to read the article.

A Personal Reflection on the development of the Service-Learning Requirement at PolyU
After Professor Yuen returned to the US in 2015, he taught a class at UCSB on Appropriate Technology, an important area related to Service Learning

Project:
The class project is based on a project implemented in Rwanda on a Service Learning courses conducted with two colleagues, Dr. Stephen Chan and Grace Ngai at the Hong Kong Polytechnic University in 2015). The learning objective of this project is:
1. To educate the students that basic engineering skills (e.g. soldering, cutting, wiring) are important for the implementation of engineering projects in developing countries
2. To recognize that advances in modern technology have led to inexpensive modular engineering components (e.g. solar panel, LED lights, batteries) which can be used to develop simple, affordable designs to address basic needs in developing countries.
