Welcome to my homepage
I am currently a senior researcher and head of 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 and Magnetism for revealing Cosmic Origins (CDMCOR), such as Early Universe, Stars, Exoplanets, and Life. I am also interested in searching for Life in the universe through Relativistic-speed nano spacecrafts.
