I am a mathematical biologist working in the field of theoretical evolutionary ecology. My
research focuses on assessing the ecological and evolutionary dynamics of infectious disease
systems to understand, for example, the evolution of host resistance to disease and how
parasites evolve to counter these resistance mechanisms.
The evolution of host-parasite range.
The American Naturalist, 176:63-71
Resistance is futile but tolerance can explain why parasites do not always castrate their hosts.
The implications of coevolutionary dynamics to host-parasite interactions.
The American Naturalist, 173:779-791
The role of ecological feedbacks in the evolution of host defence: what does theory tell us?
Phil. Trans. R. Soc. B, 364:27-36
The maintenance of host variation in tolerance to pathogens and parasites.
Deleterious mutations can surf to high densities on the wave front of an expanding population.
Molecular Biology and Evolution, 24:2334-2343
Which species will succesfully track climate change? The influence of intraspecific competition and density-dependent dispersal on range shifting dynamics.
