Like many young people, I wanted to be an engineer for practical reasons, but I accidentally entered physics when Peking University picked me into their physics department in 1977, the first year China restored its college admission system after the cultural revolution. This was really a fortunate accident, because I found myself loving physics ever since.

The most amazing thing about physics is that it presents a coherent view of the world around us. Physics theory and its beautiful mathematics really works. One can make predictions and do experiments to verify them not only qualitatively but also quantitatively. I sometimes feel superior as a physicist, because we know the world much better than most people.

When I started working on my Ph.D., I began to learn that the world is actually more mysterious than I thought. This was not because my initial impression of physics was wrong, but because, by that time, I had acquired a higher standard for understanding the world. This was the time when I began to see the boundary between our coherent knowledge and the unknown.

Working in this frontier of knowledge is what we do in physics research. I have gone through the typical career stages as a graduate student, a postdoc, and as a professor, initially with guidance from my mentors, then becoming independent and starting guiding younger people myself. We physicists travel to many places in the world and meet all kind of smart people. We look for puzzles and solve them. We pick up small pieces of knowledge and fit them into the coherent theory of physics. We have great fun playing this kind of game, but it also comes with a lasting satisfaction as we contribute to building this ever greater body of physics for humankind.

This frontier is expanding in all directions. Some of my colleagues study extremely high energies and small length scales; some go to extremely low temperatures and seek ever precise control of atoms; and some try to solve the energy crisis of our society once and for all. Some people, including myself, try to achieve a clear understanding of condensed matter, including solids and liquids, where things are very complex. My particular specialty is to see how geometry and topological principles emerge in the quantum mechanics of condensed matter. Such principles are highly valued because they seem to govern a really diverse set of phenomena. You can have a look of my CV for a more close-up description of this kind of research.
