I am an evolutionary ecologist interested in the ecological mechanisms of short-term evolutionary change in natural populations. Research in my lab investigates the biotic and abiotic factors influencing the strength and mode of selection and genetic and environmental constraints on adaptation. These include interactions between closely associated species, and the effects of food, predators and climate on adaptation. I am also interested in the evolutionary consequences of social interactions including maternal effects and effects of the local social neighbourhood on adaptation. I use observational and experimental approaches in the field and in captivity, as well as a variety of quantitative statistical techniques, but these are motivated by a core interest in understanding the causes and consequences of natural variation in wild populations.
