I use computational modeling for thought experiments and theorizing social phenomena typically in the field of group behaviors. I hold a belief that the social phenomena we observe at the societal level can be examined as emergence of individual behaviors at the micro level. How the behaviors emerge and what mechanism drives the emergence thus become my main research agendas. In particular, I am interested in how social networks play a role in the emergence of behaviors, such as social epidemics, cooperation, trust and fairness that have been widely discussed in the social sciences.
