Welcome to my page!
​
I am an astronomer and an educator. I have been working in observational astronomy and cosmology over the last 20 years.
​
At present, I am a professional-track faculty at the Department of Physics and Astronomy, University of South Carolina. I am also an Adjunct Faculty at the Centre for Space Studies, American Public University System.
​
My research is focused on Supernova Cosmology and distance scales. I study the expansion of the Universe using various calibration methods. I am involved in a collaboration to solve the so called Hubble Tension. Our recent meeting What's under the H0od? Towards Consensus on the Local Value of the Hubble Constant was held at the International Space Science Institute, Switzerland.
I also study astrophysical systematics than may improve our understanding about the nature of Dark Energy.
​
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 served as an Astronomer at the US Naval Observatory as a GS-13 federal employee. I briefly served as a Resident Astronomer for the Hobby-Eberly Telescope at the McDonald Observatory, Fort Davis, TX.
Prior to that, I received President's International Postdoctoral Fellowship from the Chinese Academy of Sciences. This fellowship gave me the opportunity to work at the Purple Mountain Observatory in Nanjing, China with Professor Lifan Wang. 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 and Chris Lidman.
​
​My main collaborator is the Carnegie Supernova Project. I am also affiliated with the Rubin Observatory's Legacy Survey of Space and Time. I was builder member of the OzDES collaboration.
