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).
