Welcome to my homepage! I am Seunghyun, you can see the pronunciation of my name here. I also go by Sky. Here is a copy of my CV.

I am a 4th year PhD student in the Department of Statistics at Columbia University, co-advised by Profs. Sumit Mukherjee and Yuqi Gu. Before coming to New York, I received my undergraduate degree in Statistics and Mathematics from Seoul National University in 2021.

I am interested in statistical inference for graphical models, through the lens of applied probability and psychometrics. Below are more details:

• Theory: limit theorems on Markov random fields (such as Ising models), variational approximation of high-dimensional distributions

• Methods: identifying and estimating discrete latent variable models

• Applications: psychometrics (cognitive diagnosis modeling), unsupervised learning.

In my spare time, I enjoy playing table tennis, board games, and swimming. I am a wine lover, and I have the WSET level 3 award in wines. I have a pet dog (she is also named Sky) back in Korea.
