I'm an associate research fellow at the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA), working on extragalactic astrophysics, with emphasis on galaxy formation and evolution, and clusters of galaxies.

I got my B.Sc. in physics from National Taiwan University (NTU) in '99. After that I went to the University of Illinois at Urbana-Champaign for graduate school, working with Prof. Joe Mohr on various topics related to clusters of galaxies.

I obtained my Ph.D. in astronomy in Aug '05, and was awarded a Princeton-Católica fellowship ('05-'08). I first spent 6 months in the Department of Astrophysical Sciences in Princeton University, then moved to Santiago, Chile, working in the Departamento de Astronomía y Astrofísica, Pontificia Universidad Católica de Chile, for one year, and returned and stayed in Princeton until Oct '08. While in Princeton, I worked on projects related to the Atacama Cosmology Telescope (ACT) and Sloan Digital Sky Survey (SDSS), and collaborated with Profs. David Spergel, Michael Strauss and Jerry Ostriker.

I then moved to the Institute for the Physics and Mathematics of the Universe (IPMU, now Kavli Institute for the Physics and Mathematics of the Universe), the University of Tokyo, first as distinguished postdoc ('08-'10), then long-term scientific associate ('10-'11). At IPMU, I worked on SuMIRe (Subaru Measurement of Images and Redshifts), a project to built ambitious instruments for the Subaru Telescope. The instruments are Hyper SuprimeCam (HSC) and Prime Focus Spectrograph (PFS). With these, we will be able to explore distant universe, understanding the formation and evolution of galaxies, as well as the nature of dark matter and dark energy that govern the dynamics and fate of the universe. The survey with HSC started in Spring 2014, and will last for 6 years. The first light of PFS is expected in 2019, and the survey may start in 2020.

I returned to Taiwan in 2011. I'm still devoting my time to SuMIRe, as well as other projects described in my (new) research page (the old research page is still a fair description, albeit a bit outdated). Feel free to stop by my office to chat about research opportunities, or drop me an email. See this page for contact info.
