Research interests:
Amphibian biology
Emerging wildlife diseases
Environmental stress

My research concerns the impact of environmental stress on native amphibians of Canada. We have been assessing the chronic effects of pesticides, particularly those that are immuno-suppressive or are endocrine disruptors. As well, we are tracking two lethal emergent diseases of native amphibians, involving the pathogenic ranavirus and the chytrid fungus Batrachochytrium dendrobatidis, in an attempt to model and retard their transmission.
