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.

Curriculum Vitae


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.

I teach master-level courses, Galaxy Formation and Evolution (together with Dr. Yen-Tin Lin), and Advanced Observational Astronomy, in the Astrophysics Institute of the National Taiwan University. I supervise undergraduate summer students and master/PhD level graduate students. I also engage in ASIAA's public outreach activities.

I am currently the project scientist of ALMA-Taiwan. My task is to promote ALMA-related research in the astronomical community in Taiwan, and to enhance the collaboration and communication with other ALMA communities in East Asia and North America.


I am fascinated by the night sky and the universe. I often travel to dark places in Taiwan and Hawaii, to enjoy the stars and to take pictures of them. I also occasionally travel to the southern hemisphere to see the Milky Way, Southern Cross, and Magellanic Clouds. For the photography, I use digital cameras and amateur-class telescopes. Selections of my astronomical pictures can be found on my Astrobin and Flickr albums.
