Research: Collective
decision making in animals
.............................................................................................................................................
I apply
theoretical and experimental approaches to a wide range of evolutionary
and
ecological questions. My main current research interest is in animal
collective
decision-making. Collective decisions depend on the relevant
information that
individual group members hold, the dissemination and use of this
information
and, not least, on the conflicts of interest between group members.
While
cooperative sharing of information often benefits most group members,
conflicts
of interest often hamper such cooperation. How groups of individuals
solve this
dilemma is crucial for the efficiency of their decision making and also
for the
social stability of their group. The required collective decision
making
processes are shaped by natural selection. They consist of
inter-dependent
individual strategies that combine in a complex manner to a collective
outcome.
I study the evolution of decision making strategies at the level of
individual
group members and the consequent collective decision outcomes at the
level of
the group. The overall aim is to understand and predict collective
behaviours
in social animals.
