Graduated from UC Berkeley with an M.S. degree, I am a registered professional engineer with 15 years of work experience. I found my passion for teaching when I started tutoring my own son. He is in a gifted school, and his math is 3-grade levels above his peers. I believe more students can benefit from my strong background in math and physics. I am also a native mandarin speaker and I will be happy to help people who are interested in learning the Chinese language.
