Biography
I am a Senior Researcher at the Institute for Data Innovation in Science, Seoul National University. (Mentor: Prof. Sungkyu Jung) My primary research interest lies in nonparametric analysis on non-Euclidean space, developing statistical methodologies for complex geometric data. I apply these methods to challenging real-world problems, including distributional data analysis (e.g., fine dust data) and network analysis (e.g., New York taxi data). I received my Ph.D. in Statistics from SNU in Feb, 2025, under the supervision of Prof. Byeong U. Park.

For those who visited my poster at 'IMS-APRM 2026'
I have attached a summary handout of 'Local Fréchet Regression with Toroidal Predictors', which I presented at The Chinese University of Hong Kong in June 2026. This document outlines the core framework, minimax optimal rates, and mathematical details of the proposed estimators.
