across the universe

I am a research fellow at the Institute of Astronomy & Astrophysics, Academia Sinica (ASIAA), working on topics related to galaxies and galaxy clusters, and a bit of cosmology.

Here's a brief description of my trajectory: I got my B.Sc. in Physics from National Taiwan University in 1999, then went to the University of Illinois at Urbana-Champaign for my Ph.D., working with Prof. Joe Mohr.  After graduating in Aug. 2005, I became a Princeton-Católica Fellow (2005-2008).  I spent two years in the Department of Astrophysical Sciences in Princeton University, and one year in the Departamento de Astronomía y Astrofísica, (now Instituto de Astrofísica) Pontificia Universidad Católica de Chile in Santiago, Chile.

During my time at Princeton and Santiago, I was part of the Atacama Cosmology Telescope (ACT) and phase 3 of Sloan Digital Sky Survey (SDSS-III), 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 IPMU), The University of Tokyo, first as a distinguished postdoc (2008-2010), then a long-term scientific associate (2010-2011).  At IPMU, I joined the Subaru SuMIRe project, which consists of Hyper Suprime-Cam (HSC) and Prime Focus Spectrograph (PFS) instruments.  I chaired the HSC Galaxy Cluster working group from 2010 to 2017, and have been contributing to the PFS galaxy evolution science pillar by obtaining deep near-IR imaging data over HSC deep fields (serving as the near-IR data coordinator).

After officially joining ASIAA in 2011, I continued to work on HSC and PFS, and then was involved in SDSS-IV.  Now I am a member of the Legacy Survey of Space and Time of the Vera Rubin Observatory.  Using data from all these large sky surveys, my group members and I have been exploring a wide range of topics in galaxy formation and evolution, clusters of galaxies, active galactic nuclei (AGN).  I am also the principle investigator for ALTA, ASIAA's program to access the twin Magellan Telescopes.

I have been fortunate to work with many talented students and postdocs.  Feel free to drop me an email (see my contact info) and discuss with me about potential projects!
