I am an astrophysicist, leader, mentor, teacher, and AAS astronomy ambassador. I am also a Senior Staff Astronomical Data Scientist at the Space Telescope Science Institute (STScI). I work for one of its goals, "make the world's astronomical information accessible to all" at the Mikulski Archive for Space Telescopes (MAST).
My research interest lies in near-field cosmology. I am particularly interested in the first stars and galaxies and cosmic chemodynamical evolution by studying ancient, most metal-poor stars still living today.
Before my current position, I was a JINA-CEE postdoctoral fellow in the Department of Physics at the Univerisity of Notre Dame and Joint Institute of Nuclear Astrophysics- Center for the Evolution of the Elements (JINA-CEE). I also taught university introductory physics courses at the Univerisity of Seoul, Korea.
