Hello!
I am a fifth-year PhD student in the Department of Statistics at UC Berkeley. I am lucky and grateful to be advised by Ryan Tibshirani. From 2015-2021, I did my B.S. in Mathematical Sciences and B.A. in Economics in Seoul National University in South Korea. From 2017-2018, I served in the Republic of Korea Army.
Outside statistics, I enjoy swimming, tennis, running, volleyball, piano, and reading; and I am a three-time winner of Jerzy Neyman Foosball Tournament hosted by the Statistics Graduate Student Association (SGSA).
Research Interests
My research interests lie in statistical analysis and methodology on deep learning. I aim (i) to understand statistical properties of modern deep learning models and phenomena, and (ii) to draw statistically rigorous conclusions, covering generalization, forecasting, and uncertainty quantification.
Recently, I have grown interested in the AI safety, interpretability, and AI for sciences, and am exploring the field through a statistical perspective. I am happy to chat about the questions and agenda in this space. For those interested, the Berkeley AI Risk Speaker Series is running on campus this semester (organized by Will Fithian and Wes Hoilday).
