About me


Position: Assistant Scientist

Institution: National Radio Astronomy Observatory

Location: Charlottesville, VA, USA

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 an assistant 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 and contribute to the development and testing of the data reduction pipeline. My research mainly focuses on the atomic and molecular gas contents in galaxies, the active galactic nuclei and supermassive black hole, stellar dynamics and Bayesian data analysis.

I graduated from Seoul National University in Korea where I was a under/grad student in Astronomy program and had M.S. and B.S. degree. After compulsory military service in Korea, I moved to USA and graduated from the University of Massachusetts at Amherst with PhD. in Astronomy.

After two years of my postdoc at George Mason University, I moved to the Netherlands and have worked at Leiden observatory for 2 years as a postdoc. Then I came back to USA and started work at NRAO as a data analyst. While I was working as data analyst, I have done the quality assurance analysis of ALMA data for PIs and been involved in software development and testing. Since I graduated, I have been very fortunate to be in the right time, at the right place and with the right people to build valuable expertise in order to establish my career and become a NRAO staff scientist.
