I am an Astronomer at the US Naval Observatory at Washington, DC. I am also an Adjunct Faculty at the Centre for Space Studies, American Public University System, where I teach online course in astronomy and astrophysics. 

​

Previously, I was a  Postdoctoral Research Associate at the Department of Physics and Astronomy at the Texas A&M University. Prior to that, a Postdoctoral Fellow at the Observatories of the Carnegie Institution for Science located at Pasadena, California. I was a Resident Astronomer for the Hobby-Eberly Telescope at the McDonald Observatory, The University of Texas at Austin. I live in Fort Davis, TX on top of Mt. Locke. Before that, I was a President's International Postdoctoral Fellow of the Chinese Academy of Sciences. I was working at the Purple Mountain Observatory in Nanjing for the Antarctic Transient Survey. I have pursued doctoral study in Supernova Cosmology from the Centre for Astrophysics and Supercomputing, Swinburne University of Technology under supervision of Professor Jeremy Mould.

​

My research interests in  supernova cosmology are: classification, photometry, spectroscopy, lightcurve fitting, host galaxy photometry and spectroscopy, cosmology fitting, and superluminous supernovae.

​

My latest paper on the correlation between Type Ia Supernovae and their host galaxies can be found in the link below:
