Career
Kacelnik heads the Behavioural Ecology Research Group at Oxford. The author of nearly 200 peer reviewed publications, his research focuses on the evolution of behaviour and mathematical modelling. His work uses an interdisciplinary approach, combining data and methods from zoology, psychology and economic theory.
In 2011 Kacelnik was honoured by the Comparative Cognition Society for his contributions to the field of animal cognition.
Kacelnik is best known for his research on tool-making and tool-use in New Caledonian crows. However, his research has involved many other species of animals, especially starlings and cowbirds, and he has made many contributions to optimal foraging theory, mechanisms of animal decision making, and brood parasitism.
