Research interests

1. A predictive framework for ecological demography. If we are to predict the impacts of climate change, invasive species and ecological management strategies on natural systems, we need mathematical tools that can cope with 3 critical problems: uncertainty, data quality, and complexity. In collaboration with Stuart Townley, I am engaged in the translation and development of tools that describe the robustness of empirical ecological models. Rather than focus on our own pet models, we should study the predictions of nearby models and transient dynamics. I have developed Daphnia as a model system to study the impacts of ecological disturbances and perturbations on population dynamics. This work has relevance to conservation strategies, invasion dynamics, and evolutionary fitness.

2. Maintenance of diversity in natural systems. Everywhere we look, we are surrounded by spectacular biodiversity. How is this diversity maintained in the face of competition and natural selection? I study mechanisms that help promote and maintain biodiversity, in diverse systems including baculoviruses, wild Brassicas, aphid parasitoids, Daphnia, farmland mammals and insects, and bacterial microcosms. Recent collaboration with Angus Buckling has developed the Pseudomonas model system for the study of relationships between diversity, parasitism and ecosystem functioning.

3. Sex and parasites. I have an enduring fascination with the evolution of sexual diversity and the virulence of parasites. This has lead to various collaborations and the study of male investment in ejaculates, sexual dimorphism in lizards, host-parasite coevolution, facultative parthenogenesis and promiscuity.

4. Statistical methods for modern ecology. I work with ecologists and evolutionary biologists to ensure the use of correct and elegant statistical analyses in empirical research.
