Welcome to my homepage
I am currently a senior researcher in Theoretical Astrophysics Group (TAG) at Korea Astronomy and Space Science Institute (KASI). I am also Professor at Korea University of Science and Technology. Before, I was a prize postdoctoral fellow at Canadian Institute for Theoretical Astrophysics (CITA). Previously, I was an Alexander von Humboldt fellow in Germany. Before that, I was a CITA postdoctoral fellow. I obtained my Ph.D. from the University of Wisconsin-Madison under the supervision of Prof. Alex Lazarian. My main research focuses on understanding Cosmic Dust, Ice, and Magnetism for revealing Cosmic Origins (CDM-COR), such as Early Universe, Stars, Exoplanets, and Life. I am also interested in searching for Life in the universe through Relativistic-speed nano spacecrafts.
