About

I am an astronomer at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) in Taiwan. My research is about undserstanding the radiation output of the universe across the electromagnetic spectrum as a probe of cosmological galaxy formation. I also work on galaxy proto-clusters, the progenitor structures of galaxy clusters in the early universe.

Before back to Taiwan, I was a CCAPP fellow at the Ohio State University in 2019-2021 and a postdoctoral fellow at Johns Hopkins University in 2016-2019. I briefly held a position at the University of Tokyo as a JSPS fellow during summer 2016 after obtaining my Ph.D. at the University of Texas at Austin.
