I study the ecology of parasites in wildlife populations. I am particularly interested in understanding the role that parasites play in food webs, and in the synthesis between ecology and the evolution of diseases.
My studies have explored the effects of parasites on the structure and dynamics of food webs in stream ecosystems of the New Jersey Pinelands.
Recently I also focused on the dynamics of parasite populations that infect wild macaque monkeys and the dung-feeding beetles that they eat on Yakushima Island, Japan.
Presently at CIDD I am collaborating on a project that uses a combination of laboratory and field experiments to examine the effects of climate change on the transmission dynamics of nematode parasites in wild European rabbit hosts in Scotland.
The unifying theme of my research projects is:
- Measuring the direct and indirect costs that parasites have on host populations and the communities of which they are a part
- Elucidating how changes to food web structure and natural enemy associations affect the evolution of parasite transmission strategies
