* Research at KAIST (2011 ~ 2016)
​My research focuses on mining and modeling large social and information networks to study their structural properties (e.g., identifying community structure) and behaviors (e.g., analyzing information diffusion).
​For more details, please check my research statement (last updated: Mar. 2018) and the list of publications.
