Kasimir is a Postdoctoral Prize Research Fellow in Sociology at Nuffield College at the University of Oxford. In his research, he studies how socio-demographic similarities and differences structure social integration in diversifying European societies. He focuses on three different, yet related settings where individuals may experience diversity through interacting with others from their own or other backgrounds: civic organisations (e.g., sports clubs, cultural associations), neighbourhoods, and coresidential partnerships (i.e., romantic unions).
His work on civic organizations studies their potential for stimulating mixing across group boundaries such as socioeconomic status, gender, and ethnicity as key dimension of social inequality. His Ph.D. thesis entitled "Who (else) is Involved? How Voluntary Associations Connect and Separate Us?" includes four chapters that examine (i) how gender segregation structures civic life, how the socio-economic composition of individuals ego-centric networks change after joining civic organizations, (iii) how participatory inequalities change as adolescents grow older, and (iv) how ethnic segregation unfolds both between and within civic organizations. It won the 'Best Dissertation Award' of the German Academy of Sociology and received the second place for the ECSR's 'Best Thesis Award'.
In his work on neighbourhoods, he examines patterns of residential segregation and study in how far individuals prefer to reside in places where their neighbours are similar to themselves regarding age, ethnicity and education level. He compares these patterns to the organisational context, too.
A final strand of his work focuses on partner choice in ethnically diverse contexts. Using full-population register data from the Netherlands, he examines, among other things, partnership formation between different minority groups, long-term singlehood as an outcome of the partner search process, and the partner choices of individuals of mixed ethnic backgrounds.
