One of the ultimate goal of physics, astrophysics and astronomy is to understand the origins of the universe. To do that requires the understanding of the underlying laws that govern the universe. In our laboratory, we are working on developing gravitational wave astronomy, which is a new way of observing the universe, which we believe will bring us closer to our goal. In addition, we also do research on quantum optical techniques (e.g. squeezing), thermal noise, and vibration isolation techniques, for use in relativity and other fundamental physics experiments. Furthermore, R&D to make space based gravitational wave telescopes a reality is also conducted here.
