Research

Short Bio

I am an Astronomy professor at the Physics & Astronomy Department of the University of Iowa. I use observations across the electromagnetic spectrum to study the evolution of massive galaxies. I obtained my B.S. from Nanjing University in 2003 and my Ph.D. in 2008 from the University of Hawai’i (Advisor: Alan Stockton, Thesis: Extended Emission-Line Regions: Remnants of Quasar Superwinds? ). After postdocs at the California Institute of Technology and the University of California, Irvine, I joined the faculty of the University of Iowa in 2013. Here is a brief two-page Curriculum Vitae as of 2021.

Research Interests

My research is in the field of galaxy formation and evolution. Previously, I have studied quasar extended emission-line regions, dual active galactic nuclei, and gravitationally lensed starburst galaxies. I have observed these fascinating objects with integral-field spectroscopy, adaptive optics, radio interferometers, and space-based telescopes. Currently, my research interest focuses on understanding the nuclear activities triggered by galaxy mergers with SDSS-IV/MaNGA integral-field spectroscopy, probing dark matter in high-redshift star-forming galaxies with gas kinematics from ALMA, and tracing the large-scale gas supply of high-redshift starburst galaxies with quasar absorption-line spectroscopy.
