I am a Postdoctoral Researcher at the Columbia University Mailman School of Public Health, where I am fortunate to be mentored by Professors Elizabeth Stuart, Kara Rudolph, and Caleb Miles. I obtained my Ph.D. in Statistics from Rutgers University in 2025 under the supervision of Professors Zijian Guo and Nicole Pashley. Previously, I earned my master's degree in Statistics from Seoul National University in 2020 and my bachelor's degree in Mathematical Science from the same institution in 2018.
