The Epoch of Reionization
Constraining the timing and spatial topology of reionization with Lyman-alpha emission, damping wings, and ionized bubbles.
Assistant Professor · Early Universe Group Lead
We study the first billion years of cosmic history, with emphasis on high-redshift galaxies, Lyman-alpha emission, galaxy physical properties, and the large-scale structure of reionization.
About
I am an Assistant Professor in the Department of Astronomy & Space Science at Chungbuk National University and lead the Early Universe Group. My research focuses on observational probes of cosmic reionization, high-redshift galaxy formation, Lyman-alpha emission, Lyman-continuum escape, chemical evolution, and machine-learning applications to galaxy surveys.
Before starting my faculty position, I was a postdoctoral fellow at the Space Telescope Science Institute and a JWST postdoctoral researcher at NASA Goddard Space Flight Center. I received my PhD in Astronomy from the University of Texas at Austin.
Research Themes
Constraining the timing and spatial topology of reionization with Lyman-alpha emission, damping wings, and ionized bubbles.
Measuring star formation, metallicity, ionization conditions, and internal structure in early galaxies with JWST and next-generation facilities.
Applying statistical modeling and machine learning to reconstruct early-universe physical properties and three-dimensional reionization structure.
For Prospective Students
Students and early-career researchers interested in high-redshift galaxies, JWST spectroscopy, galaxy evolution, reionization, Lyman-alpha emission, or data-intensive astronomy are encouraged to get in touch.
