We study how evolution and ecology shape the biological diversity of natural populations. We aim to understand the effects of both genetic and environmental effects on animal life histories. This includes how climate change is affecting wild animal populations today, as well as studies of the genetic basis of quantitative traits, natural and sexual selection, inbreeding depression, senescence, phenotypic plasticity and maternal effects. Most of my work has been on wild vertebrate species, in particular in studies where we have long-term records over several decades of a population, but I've also worked with collaborators on a range of lab, domestic and plant populations.

In a changing world, species must constantly cope with predictable and unpredictable environments.
All across the world, species’ populations and the biodiversity of ecological communities are changing in complex ways.
Condition has been a central concept in evolutionary ecology for decades, but recent discoveries challenge our understanding of the nature of condi
The adaptive significance of animal coloration is clear: it matters for survival (camouflage, warning coloration, mimicry) and it matters for repro
