I enjoy teaching because for me it is a special way of learning -- one always learns so much more, when one tries to teach a subject well.

I started teaching once I finished high school, throughout my own undergrad studies, up to my current position. I am happy to say that I've taught/tutored in every single educational institution that I have been at: high school, NTU, NUS, TU Delft, FU Berlin, and now back at NTU again. The most rewarding part of teaching is to see your students gaining appreciation and passion for the beauty of science, instead of being concerned about simply solving another problem, or getting a higher grade. I have increasingly found that this is even more 

Teaching, when done well, is a job that serves others with wisdom, integrity and humility, which is rare in today's world. We are in need of better educators.
