I am a professor of Theoretical Cosmology at the Center for Theoretical Astrophysics and Cosmology (CTAC), the Department of Astrophysics (ICS) and the Physics Institute (Physics), University of Zürich (UZH). My research interest lies in understanding the origin and evolution of the Universe with large-scale structure probes.

I was born in Seoul in 1975, got the undergraduate degree at Seoul National University (SNU), and served in Korea Army, before moving to the Ohio State University (OSU) in the USA for PhD degree. I was a Donald H. Menzel fellow at the Harvard-Smithsonian Center for Astrophysics (CfA), a Berkeley-Zürich Cosmology fellow at Lawrence Berkeley National Laboratory (LBL), and a SNF Ambizione fellow at University of Zürich, before I joined the faculty in 2014 at the University of Zürich. I won a European Research Council Consolidator Grant Award (ERC-2015-CoG). A brief cv (pdf).

SCIENCE

I am primarily interested in theoretical astrophysics and cosmology. I use large-scale structure probes such as galaxy clustering, weak gravitational lensing, and cosmic microwave background to understand how the Universe started and evolved until today and to test gravity theories on cosmological scales.

Over the past decades we have learned a lot about the origin and evolution of our Universe, and the standard model of cosmology can explain a vast amount of cosmological observations from the galactic scales to the observable horizon. However, despite its astonishing success, the physical nature of its ingredients still remains elusive.

The ultimate goal of my research is to explore the dark sector of the Universe and to understand the physical mechanism of perturbation generation in the early Universe. My research involves lots of analytic and numerical computations.

CLASS

I teach Physical Cosmology in the Spring semester and General Relativity in the Fall semester. An interactive course for PhD students “Astrophysical Thinking” is also taught in both semesters.
