Curriculum Vitae: cv.pdf


I am an assistant professor at Indiana University School of Informatics and Computing and a co-founder of Janys Analytics. 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 from June 2008 till May 2011. My post-doctoral advisor was Albert-László Barabási. I received my Ph.D. from Physics Department at KAIST in early 2008. My advisor was Hawoong Jeong.

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 covers several area such as the hierarchical & modular structure in social and biological networks (e.g. Nature 466, 761-764, 2010, Science 333, 601, 2011), the analysis of metabolic networks (e.g. PNAS 107, 1082-1087, 2010), social media (e.g. twitter - pulse of the nation), and food (Sci. Rep. 1, 196, 2011).
