About Me:
I am a graduate student in astronomy at Seoul National University. I study how galaxies build up their stellar mass and how that stellar mass is distributed through a galaxy cluster, using clusters — the densest environments in the universe — as my laboratory. My research combines deep spectroscopic surveys with SED fitting to characterize the stellar populations of cluster galaxies, building stellar mass and luminosity functions with careful completeness corrections. To connect projected observations to the physical properties of clusters, I developed an analytical deprojection model that recovers three-dimensional stellar mass profiles, and I test my results against hydrodynamical simulations such as IllustrisTNG. I also work on observing proposals for Gemini, Subaru/PFS, and MeerKAT.
I love to watch and play various sports. I enjoy following the NFL, NBA, MLB, KBO, UEFA Champions League and F1, and I also love playing basketball, soccer, tennis, swimming, and board games. I am extroverted, energetic, and enthusiastic — someone who genuinely loves meeting new people and making friends!
I am preparing for Ph.D. applications for Fall 2027. The questions I care about extend well beyond clusters, and so do the tools: SED-based stellar-population inference, completeness modeling, and confrontation with simulations apply wherever galaxies are counted and their stellar populations measured — from the baryon census around transient host galaxies, to the assembly of stellar mass at high redshift, to the design of next-generation spectroscopic surveys. I am eager to carry them into new regimes and datasets.
