Teaching at Capitol since: 2001

Why did you first become a professor?

I like teaching. I enjoy teaching students, and I like it when students ask me questions I don’t know. That challenges me, pushes me to learn more and helps me to improve. No one knows everything, so this helps me learn more.

What is your favorite part of teaching?

Being asked and then answering the questions [of my students]. It’s not only in the class, too. Students can ask me anything; I hope I understand it and know the answer. If I don’t know what they’re asking, I hope I can learn from that.

We should always update our information. 20 or 30 years ago there were no computers. Now everyone should learn how to use them. And teachers need to learn how to post on blackboard and do other things, that’s an example of staying updated.

Why Capitol? What makes it different?

First, it’s a good community. There are many nice people and colleagues.

Second, we can help each other here. So, the people here can help me learn more. Because I’m a foreigner, some people here have helped me learn and become familiar with American culture.

How has your career prior to teaching affected your teaching? How important has your experience been?

I worked in engineering in China for almost 15 years. First as a technician for three years and then as an engineer for 12 years. Those years of experience have helped me teach the students, a lot of applications such as how elevators work and how camera flashes work. The capacitor that works when a camera flashes is a good example to use when explaining capacitors to students. Other engineering experiments I’ve done are also good for helping explain things to students.

We need to have good leaders to teach the next generation and give them direction. Not just in the class, but in everything - how to research and figure out problems. Once we give them direction, they can learn how to do things for themselves, and learn for themselves.

What are some of your proudest academic/professional achievements?

My research. I did some research on protocol for wireless networks, but that has stopped. Next, I’m doing renewable energy research. I’m trying to think about what is the most efficient way [to make renewable energy].

What are your hobbies/interests outside of work? What is something your students might not know about you?

I like tennis, and table tennis. I also like playing Chinese chess. It’s a fun game and it’s a little different from American chess. I also like playing weiqi, which is a popular game in Asia. You have to be smart to play, because you not only see one pawn, you have to see the whole board.
