Bio

I received my Ph.D. from the Physics Department at KAIST in early 2008. My advisor was Hawoong Jeong. From June 2008 to May 2011, I was a postdoctoral researcher at the Center for Complex Network Research at Northeastern University and a visiting researcher at the Center for Cancer Systems Biology at Dana-Farber Cancer Institute. My post-doctoral advisor was Albert-László Barabási.

Interests

I am interested in the structure and dynamics of complex systems, such as society and living organisms. So, I usually play with massive datasets and muse on the hidden patterns. My recent work mainly focuses on the hierarchical & modular structure in social and biological networks (e.g. Nature 466, 761-764, 2010), the analysis of metabolic networks (e.g. PNAS 107, 1082-1087, 2010), and the social media (e.g. twitter – pulse of the nation).
