Research Interests
Sitting primarily within the traditions of analytical and mathematical sociology, Cohen's research focus is network formation — i.e., where do networks come from? And he is especially interested in the emergence of social networks that span small-scale traditional human populations — i.e. microcosms wherein supportive relationships (e.g., friendship, advice, financial aid, food provision, and physical assistance) facilitate day-to-day survival by offsetting the challenges of poverty, subsistence-based living, and limited access to protective institutions (e.g. state welfare).
Cohen also has a deep interest in evolutionary and sociological theories of human sociality (e.g., kin selection theory; structural balance theory), genetic kinship, and ecological arguments around how variation in individuals’ social and physical environments shape their (relational) behaviour. When appropriate, he makes a special effort to draw on zoological research on the social networks of non-human animals. And he is generally interested in interdisciplinary applications of network analysis and mixing social and evolutionary science.
