Jinhyuk Yun

Physicist - Data Scientist | jinhyuk.yun_at_ssu.ac.kr


I am an assistant professor at School of AI Convergence, Soongsil University.
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. ently I am working on:
- Modeling Human Behavior
- Network Science
- Data Science
- Computational Social Science
- Cultural Science
- Scientometrics
- Citation Dynamics
