Professor Alex Kacelnik is a behavioral ecologist and the head of the Behavioural Ecology Research Group at the Department of Zoology, Oxford University. His main interest is in decision-making from the joint perspectives of evolutionary biology, ecology, comparative cognition, and economic theory. His research group has two main streams of experimental research, one dealing with the use of tools by New Caledonian crows and the other with the problems raised by decision making under risk (or stochasticity) in starlings and humans.
