Professor Tommaso Pizzari

Research Interests

I am interested in the evolutionary ecology of sexual behaviour, and most of my work focuses on resolving different aspects of sexual selection and intersexual coevolution, using the fowl, Gallus gallus, as a model species which enables me to use a combination of experimental work, and physiological and molecular tools. 

Additional Information

I have served on the NERC Peer review panel, the ASAB council grant committee, the BOU council, as well as on the editorial boards of several journals including American Naturalist, Animal Behaviour and Proceedings of the Royal Society B. I was awarded the ASAB Outstanding Young Investigator Award in 2005, and the Philip Leverhulme Prize in 2008, and the Scientific Medal of the Zoological Society of London in 2015.
