I am an evolutionary biologist working at the University of Exeter. My main interest is in trying to understand how genes and environments interact to determine the way in which animals evolve. This means my work is about 50% ecology and 50% genetics. I study a wide range of animals -from insects to humans - but tend to focus mainly on fish, birds and mammals.
