Research interestI am an evolutionary ecologist and my work focuses on the processes that create, alter and maintain biodiversity. I am especially interested in the interplay of ecological and evolutionary forces in shaping biodiversity between populations. But I have also a particular interest in undertsanding why do individuals differ in life history traits within a single population. Understanding how microevolutionary processes can affect individual phenotype in variable environments is fundamental to successfully manage and conserve wild populations.
My work involves a range of approaches, from controlled laboratory experiments to field work in various parts of the world. I am formely trained as a fish farmer, a marine biologist, and a behavioural ecolgist so most of my work has been on marine and freshwater fishes. ><(((º>- ><(((º>- ><(((º>- |
