About me

I am an astronomer studying how galaxies form and evolve, based on statistical interpretation of the observational data and comparison to the theoretical predictions. Currently, I am a scientist at National Radio Astronomy Observatory (NRAO) and working for the North American ALMA Science Center (NAASC). 

If you're curious what ALMA means, ALMA stands for Atacama Large Millimeter/submillimeter Array which consists of many (66 and possibly more) radio antennas and virtually forms a one big aperture radio telescope. 

My primary role in the NAASC is to support ALMA users by contributing to the development and validation of the ALMA data reduction pipeline and the data quality assurance metrics.  My broad research interest includes (1) radio-(sub)millimeter observation of galaxies and active galactic nuclei in local and distant Universe, (2) study of first galaxies in cosmic dawn using ALMA and JWST, (3) evolution of galaxies and AGNs using the data from the Legacy Survey of Space and Time (LSST) by Vera C. Rubin Observatory, (4) dynamical evolution and equilibrium of gravitational system, and (5) advanced statistical analysis of astronomical data.  

I graduated from Seoul National University in Korea with B.S. and M.S. degree in astronomy. After compulsory military service in Korea, I moved to USA and graduated from the University of Massachusetts at Amherst with Ph.D. in Astronomy in 2012. After two postdoctoral positions at George Mason University and Leiden observatory, I have been working at NRAO since 2016.
