Current Research Interests

Since I believe that a lot of mysteries of nature might be hiding in the physics of the early universemy main research interests tend to focus on topics of early universe cosmology, including the initial condition of the universe, cosmic inflation, primordial origins of gravitational waves and black holes. Besides, in recent years, I have developing interests in the nature of dark matter and dark energy and classical and quantum aspects of gravity.

I was born and grew up in Mongolia. After receiving my B.Sc. in Physics from the National University of Mongolia in 2010, I moved to Seoul for my Ph.D. study and started my ten years of journey in Korea. Supervised by Prof. Bum-Hoon Lee, I obtained my Ph.D. in Physics from Sogang University in Aug. 2016 and remained at Sogang, as a post-doc researcher in the Center for Quantum Spacetime (CQUeST), until Mar. 2017. In Apr. 2017, I joined the Center for Theoretical Physics of the Universe, Institute for Basic Science, Korea, as a research fellow and worked there for three years until Mar. 2020. Before coming to Taiwan, I held two short-term post-doc positions in the Physics Education Department of Jeju National University (Apr. 2020 – Aug. 2020) and CQUeST (Sep. 2020 – Nov. 2020). While living in Korea, I found myself interested in learning new languages. Thus, I plan to learn Chinese and hope to pass the level-2 of the HSK test when leaving Taiwan.
