My fields of interest include behavioural, chemical and molecular ecology of insects, as well as population genetics and dynamics - The reproductive division of labour in social insects, especially honeybees and the resulting potential conflicts among members of an insect colony and how these conflicts are solved. - The organisation of groups, mechanisms of coordination and task allocation and the role and means of communication in achieving coherent collective behaviour. - The self-organisation and their underlying mechanisms in social insects. - Interactions and co-evolution between host and parasites, e.g. between honeybee and small hive beetle.
