- In my research, I seek to develop our understanding of host-parasite relationships and the biology of invasions in an ecological and evolutionary context. For example, I study the role of ecological stoichiometry in the success of the non-native New Zealand mud snail and the ecological and evolutionary consequences of the introduction of lake trout to zooplankton in Yellowstone Lake. Using snail-trematode interactions, I also study the consequences of parasitism to the evolution of host-life histories and how varying the stoichiometry of food alters the outcome of snail-trematode interactions.
