ABOUT

I am a data scientist at Korea Institute of Science and Technology Information.
I am interested in the structure and dynamics of complex systems such as society, culture, media, and collective knowledge. For the purpose, I generally handle massive datasets and detect the hidden patterns beneath external appearance. Currently I am working on:
- Modeling Human Behavior
- Network Science
- Data Science
- Computational Social Science
- Cultural Science
- Scientometrics
- Citation Dynamics
