I am a research astronomer working at the Institute of Astronomy and Astrophysics of Academia Sinica, Taiwan. I spend most of my time conducting astronomical observations, analyzing the data, supervising students and post-doctoral researchers, writing papers, and serving the astronomical community. I am also an amateur astrophotographer. I like to take pretty pictures of the sky and our universe using amateur-class equipments.

My research interest is the formation and evolution of distant galaxies, and the underlying cosmology. I conduct multi-wavelength imaging observations of the early universe, to detect galaxies living therein and to characterize them, such as measuring their luminosity, mass, mass growth rate, spatial density, and large-scale structures. I often use telescopes on Maunakea, one of the best locations to observe the universe from Earth. I also sometimes use telescopes in other places, such as Chile, and in the space.
