I am interested in elucidating the forces responsible the association of lower level units into higher levels of organization and the consequences of such associations on the structure and dynamics of populations. Using a multilevel selection perspective and both empirical and theoretical approaches, current areas of research include:
- evolution of sociality,
- evolution of sex ratios in subdivided populations, and
- evolution of life history traits and local population dynamics in metapopulations.
