Professor of Evolutionary Biology
I am an evolutionary biologist whose main interest is adaptation, and especially the evolution of social behaviours, such as cooperation, altruism, spite, mutualism, and how these can influence major evolutionary transitions. I use a mixture of techniques including theory, experiment and across species comparative studies. My empirical work has utilised a range of organisms, including bacteria, protozoa, insects (especially parasitoid wasps), fish, birds and mammals. For the most up to date information on what is happening within my research group, see my publications page.
I am the Department of Zoology's Athena Swan Champion.
